EEVacademy | Digital Design Series Part 4 - Digital Logic Datasheets Explained

[@Jesse-ei6hq]

They don't bother teaching this before we use datasheets at university. Great video! Really appreciated Dave :)

[@EEVblog]

Thanks.

[@mrme3608]

I rarely comment on videos, but I had to make an exception.Thank you! This is very informative & truly a valuable resource for those of us studying.

[@EEVblog]

Awesome to hear, thanks

[@SidneyCritic]

Something for people who aren't in the industry, and delivered in a way that the general public can understand. Good vid.

[@user-su5sq5ib3i]

My college teacher would not even show us anything about them, and he is getting paid to do it. This should be taught before we started doing labs. Thank god you care enough to make this video and share it with people who WANT to LEARN! Cheers from Canada

[@mand6029]

hi Dave thank you for this walk-through , cheers from Tanzania , I appreciate your infomative and intuitive videos

[@WacKEDmaN]

do a 24hr stream on FPGAs!

[@octapc]

Thanks Dave, I watched it all the way through, brings back some memories from days of old understanding data sheets.

[@giacomo1191]

Dave, please do more videos like this. Awesome job!

[@mbaker335]

Very informative indeed. A good addition to the EEVacademy.

[@EEVblog]

Thanks.

[@kungfumaster8171]

As usual David, excellent. Thank you.

[@VoidHalo]

It's great that you made this. I got into electronics about 10 months ago and I've had a hard time finding stuff to explain logic IC datasheets in great detail. I could find info on a few parameters, but that's it. The next best thing I found was an application note from, I think it was TI about MOSFET datasheets. This will be very useful. I'll likely watch it a few times. I hope to see more in the series in the future. Thanks much!

[@dummyvariable3079]

Just remember ARTFDS: always read the fucking data sheets

[@VoidHalo]

I've watched this a few times and it's not just helped me to understand more of the stuff in datasheets, but it's helped me pay attention to it more as well.

[@EngAlperDemir]

I've always wondered if there's a complete reference for data sheets, definitely a good start.

[@tongordebeke1355]

And again I learned something, Thanks

[@caulktel]

Thanks Dave, quite informative. Hope your cold gets better🤧.

[@thecombatengineer7069]

Greetings all, just wanted to interrupt and ask a small favor. KZbin has changed their grading scale again and it is more important now than ever before to take a split second to press the "like" button for all your favorite channels. It is just one small way we can say thank you to these content providers for sharing their vast knowledge with us for free! I have seen many of my favorite channels just stop uploading content or insert ads every 30 secs and all we have to do to prevent that, is simply say thanks by pressing "like." Please and thank you.

[@migsvensurfing6310]

Exactly!

[@remontlive]

Again it's a most useful VideO I ever seen last few years

[@886014]

What a fantastic video, the mention of the old data books sure bought back memories. Excellent information.

[@al45tair]

Worth noting that it *does* matter for Icc if the input is something *other* than Vcc or 0; in particular, if you have an input floating at 0.5Vcc, Icc could be quite large, which is why the data sheet mentions somewhere that you need to be sure to tie unused inputs to Vcc or ground.

[@devttyUSB0]

Very informative. I really like most of your videos! Learning every vid. Thanks a lot!

[@johnnyprimavera2]

Another one of your masterpieces. 1000 and standing. Well done Dave!

[@dentakuweb]

I've been hoping someone made a video like this for quite some time. That was very informative and well paced.

[@AntonioBdeJesus]

As always you killed it. Thank you very much!

[@kolby4078]

I will not watch this vid but i'm happy it exists. keep doing them, its good for the real makers of the world

[@Z80user]

I'm a hobbyist and I read sometimes datasheet and I understand the most of it, but not all of course, is good for me and the rest understand datasheets (thumbs up)

[@OpenGL4ever]

I second that!

[@dipi71]

What? No mandatory orientation in the datasheet lest those electrons fall out?

[@Kabodanki]

I would love to see more of those videos, it's so important for us hobbyist who doesn't have a PhD in datasheets reading

[@OudioVisual]

Really enjoyed the video. Would love to see a capacitor datasheet showdown - Nippon chemi con vs the cheapest cap on digikey =)

[@scottycashman]

Would love to see a couple more videos on Datasheets. Especially on microcontrollers

[@UltraRik]

This was surprisingly easy to wrap my head around and amusing to watch love your vids man!

[@tomgeorge3726]

Hi Dave, Good video mate. I'm finding noobs to electronics are having problems with MOSFET datasheets, particularly when looking for Logic gate devices.

[@goose300183]

Hi Dave, thanks for the video! Prior to watching I didn't know the relevance of half of the datasheet, now I do! It would be cool to see you take a look at a very complex FPGA datasheet, or at least a single section of it. It'd be nice to know what all the voltage rails an FPGA needs are used for internally, for example.

[@bobel659]

Thanks Dave - very informative (for someone who is newish to electronics anyway). I learned quite a lot. :-)

[@brikotube]

Great job as usual. Thanks for sharing your wisdom.

[@dardosordi]

Thanks Dave, this is great. Love this kind of videos.

[@patrioticrex305]

Thank you for video. Very informative. They should include this in every engineering school

[@mrkv4k]

Just btw, those clamp diodes are usually ESD protection diodes. But even if tose wouldn't be there, if you exceed Vi above Vcc, it wil allways clamp, just with much lower allowed current.

[@andrewkowalczyk1156]

My 2 rules regarding datasheets: 1. Always read the datasheet 2. Never trust the datasheet

[@OpenGL4ever]

3. Sent a bug report if something is wrong in the datasheet.

[@rahmatdwiputra6809]

This is amaziiinngggg, thanks Dave

[@pekkagronfors7304]

Very good. Thanks!

[@whitevamp1051]

very informative, as always. thanks.

[@JohnnyTsc]

Thanks, Dave

[@SupremeCommander0]

Thank you Dave a lot! I'm gonna need to watch this one more time to remember all the things. I freakin' love electronics!

[@iuri.castro]

ADCs and precision OPAMPs datasheets would be nice Dave. Nice video btw.

[@mihai1339]

Verry good video. Big thumb up,Dave

[@olasoderlind5685]

7:11 best ring tone ever :)

[@bartomiejnozka8992]

Nice sound effect at 7:12 from Back to The Feature movie ;)

[@paulbadenhorst2981]

Yes please would like to see more

[@vladomaimun]

Awesome video! Can you go through a datasheet for an amplifier? Amps have a ton of different parameters.

[@cursoderobotica]

Nice video Dave, I have a question in regards to the software tool you use to write and paint over the screen. I am curious about that, It seems quite good to implement in my own teaching projects for my students, thank you!

[@frankgrudge8823]

Greatest vid ever Dave thanks

[@txescientist]

Great job you did there. Please do the opamp datasheet (LM358, LF351, TL084 or so...)

[@EEVblog]

I'd have to see how much of that I have covered in my 50min Opamp tutorial...

[@octapc]

EEVblog Oh please don't force me to troll through your vids to find it. Lol

[@EEVblog]

Type "opamp" into KZbin, it's usually listed #1

[@dardosordi]

I've only managed to understand opamps trough that explanation, it was great! But it will not hurt to hear it again, with expanded information. I would love it.

[@snnwstt]

You can also give a try to chapter 11 of the free edition (the 2002 one) of "Op Amps For Everyone", by Ron Mancini, for Texas Instruments. The algebraic symbols are those of TI though. www.cypress.com/file/65366/download

[@NNNILabs]

I wonder how many blown parts you've saved us?

[@ZEROSTATIC72]

Sorry to be pedantic Dave but asteix is a comic book character, I think you were referring to the asterisks in the datasheet. If we're reading datasheets then please fogive me a little pedantry. Thanks for the videos.

[@fernandovelcic]

please do it with mosfet and transistors

[@bbreeuwer4577]

About maximum ratings. In some cases your device will still run fine (as in not blow up) if you exceed, but they simply can't guarantee. Sometimes that's a little confusing, IMO that's part of recommended ratings. BTW, what I find very annoying about some datasheets is that they don't short peak currents (instead of only continues). Which can be a very important parameter when you use these things in high switching circuits.

[@bbreeuwer4577]

To maybe make this a little more clear. How should I read "continuous" output current? Is that RMS, is that just a DC current? And if so, does that mean that with a switching signal I can still just this as an RMS value? Because the peak current will be (much) higher in that case. Extremely frustrating that manufactures are not more clear with these things.

[@privatetutorials4428]

dave, we need much more about fpga

[@PlasmaHH]

If you are sending a probe to pluto you would be hand selecting very well characterized parts

[@EEVblog]

Same rules would apply, be careful you get the right characterisation parameter

[@robfenwitch7403]

Disney Corp. will have a list of approved devices.

[@jotaemebee]

Nice video!

[@bwack]

Great content. I'd like to see more of this! :)

[@uwezimmermann5427]

@37:15 and @37:48 or pages 8 & 9 of the datasheet: does TI actually claim copyright on the symbol of a NAND gate and its connection into an SR-flipflop?

[@johnplaid648]

DAY YAVE!!! You are an electronics GENIUS!!! And you flubbed the audio? Slowly all my heroes are disappointing me.

[@Audio_Simon]

Please will you do a datasheet video for a low end PIC controller? I'm just starting to dip my toes in microcontrollers. I've only touched analog before so it's a bit scary.

[@SzDavidHUN]

I'm at University. Last year we had a course about controlling techniques and EE stuff. Yeah, I like EEVBlog, and we're get more. Yeah... We shoud know this from there, and that from there style lectures. But there was the times when we did stuff on real hardware, PLC. Profi-bus, ethernet, registers, they showed us a non working pneumatic "factory" that we will make, aaaaand actullay the most advanced thing required about 10-20 relays and 4 timers. A crude traffic control lamp. Under a half year. But more than half of the students did it w/o real stuff, just computer emulator, the real hardware was a simple kit, 20 leds, 20switches, an HD44780 like LCD with some buttons as HMI device. The last was never used. We programmed in ladder logic. The only thing I learned is the opposite of set is reset. *disappointedly goes back to program esp8266 in arduino api* Sometimes I feel like Dave makes much better education than our university. If I put the same time into this channel I'd be a better EE than computer engineer now I am. I'm teaching at the university at the same time, there is a course about OS, and I teach the programming part of it, so how to use C to use the OS features, shared memory and stuff like this. I draw up the stuff for the lesson, explain it, write a program about it on the projector, make deliberate mistakes to show how not to do, while showing how to use documentation. The clear the projector, but leave all cheat stuff on the white board, and give links to official and non official documentation. "Any questions?" *silence* And 10-20% can redo the same program in 30 minutes, no question asked, any help can be used, even can work in groups. Goes around, and some folks can't even program in C, like read a file to memory then print it back out. And that isn't the first course when they use C.

[@purpleravenstar]

SzDavidHUN Nice.

[@randycarter2001]

Well you could do one for the Arduino. Something everybody's doing these days.

[@thcoura]

With sky rocket bill of materials, we need a constraint solver to help select the components. is there such thing available? I'm not saying to signoff a PCB, is before that. you have a functional idea of the project and now needs to select the components.

[@MatthewSuffidy]

Wow I used to connect up my 200 in 1 logic chips to like 5v of anything. If it was like this was there a chance of blowing the chips up? I guess FET transistors don't have that voltage drop of diodes of 1.2v. Is this why dimm memory can never go below 1.2v?

[@tbbw]

I wonder why they used 2v, 4.5v and 6v as examples instead of more common 3.3v and 5v levels in the datasheet. Is there any reason why they did that?

[@OpenGL4ever]

I would assume, standard batteries as power supply without voltage regulation where quite common in these days and this gives us: 3*1.5 V = 4,5 V 4*1.5 V = 6 V

[@meisterlumpi7822]

Awesome!

[@khronscave]

16:21 I thought the 85C max was part of the "industrial" temp range, 70C being the "commercial".

[@TomStorey96]

I guess when he says commercial he means "not military spec". Likely the non-military version is "compliant to industrial specs" because theres no point having 3 variants.

[@khronscave]

Not sure about logic chips, but opamps and such do have different variants for the "commercial" and "industrial" temp ranges, with the -C and -I suffixes respectively, for TI parts. Just sayin' :)

[@sanityd1]

Something beautiful from TI

[@user-sd7hh8ek1c]

In the "Description" section it says: Y = (not A) or (not B), but NAND is Y = not (A or B). What the hell?

[@brendanedmonds]

Can you do a video on how to create footprints inside altium or circuit studio?

[@EEVblog]

Why? That would just be a specific how-to video on how to use a $1000+ commercial package. There is no value in that apart from Altium customers.

[@yngvenystrand167]

Robert Feranec has done quite many Altium tutorials. Maybe also on footprint creation...

[@brendanedmonds]

I mean, interpreting the datasheets and creating an Altium footprint or circuit maker or any other PCB tool. Are the measurements in mm, inches, feet, meters, kilometres, etc. What does it mean when you have a number in a box. In that video, you have a number then a line underneath then a number under that, what does that mean? What does the semi-circle symbol mean? The 7400 series are relatively easy to interpret, however, when you get into some BGAs, it can be rather complex. The NorComp 684S7W2103L461 connector can be confusing as well. And it's also very important, as you have gotten it messed up in your recent nixie tube design as well. Robert Feranec doesn't have anything on footprint creation. Also, Robert can be condescending sometimes in how he explains things, although he does know his stuff.

[@RyanJardina]

More please

[@gamerpaddy]

could you do a indepth kicad vs circuitmaker vs eagle vs davecad comparison?

[@EEVblog]

Only if I spent the next month on it, full time.

[@OpenGL4ever]

Ok, could you spent a 1/4 month on kicad full time for an indepth kicad video?

[@TheEricBooth]

lol. Apologies' for poor audio quality when it's 100 times better than most videos on KZbin.

[@ricardo.mazeto]

Do I really need to go through all that current checking and ajusting in real life? Isn't there a tool that altomate all this boredomness? Like, preferably in HDL?

[@migsvensurfing6310]

Nope you have to work and think for your payment. Even those data changes if you pick another manufacturer even if the model No. is the same.

[@ricardo.mazeto]

My point is, it is suitable for automation. I'm just wondering if there's such a program already.

[@williamsquires3070]

(@ 0:11) Can anyone spot the obvious logic error on the data sheet? Hint: "#3" :)

[@gorillaau]

What is the risk when exceeding the storage temperature? Perhaps this is a devil's advocate pondering.

[@EEVblog]

That's a question for the manufacturer.

[@gorillaau]

EEVblog Fair Enough. Thanks for the reply all the same.

[@contemporiser]

So much space wasted in the first column. They could put full names next to the abbreviations

[@emi22n]

do fpga's :) please

You'd really be getting into IBIS territory at that point.
