@@QueueTeePies Yeah Ben Eater is pretty good, i think Scanlime also showed some things but can't for the life of me remember when. I think one of the most helpful resources was the Beyondlogic site from like 15+ years ago, i think once you're through that, you'll find the spec easier to parse.
Thank you very much for the work you are doing. I'm currently graduating in applied computer siences, but none of my classes really covers this real world application stuff. You are one of the people who make youtube an educational place, and not just a timewasting platform. Keep the videos coming! (Especially more general videos like this, or the MOSFET video you did)
Great video! Microcontroller and digital Logic IC datasheets arent too bad. Analog Devices can be hard as hell. I cant even identify all of the schematic symbols in the application circuits for the MC1377 and MC1374 chips.
Heh that's what I'm basically starting to do with Patreon. Also, for the new series on the evaluation boards, I'll try seeing if anyone is interested in buying some. Any other suggestions? This is certainly new to me!
Professor please help!! When I was looking for MJE13005 datasheet I found there are two parameters named as VceO(sus)=400VDc and other is Vce=700VDC, so what does these two means?? Now which one is to consider as max withstand voltage rating when choosing this bjt to switch inductive load like smps ?? Please help
8:30 A good everyday analogy for the absolute maximum ratings versus recommended operating conditions is the tachometer on a car. Imagine 9000 RPM as the absolute maximum rating and 3000 RPM as the recommended operating condition. Yes, your car can run at 9000 RPM, but only for a very short time before it destroys itself. Likewise, we humans can have body temperatures of 102 deg. F while we are fighting off a disease, but if it stays there for your normal everyday life, you need to go to the hospital.
Man it really depends. We're a design shop and not an OEM. We have to be efficient with time. It's nearly always better to make mistakes on the initial design, then fix in the next revision, rather than spend hours and hours trying to get the initial design perfect (which still never happens).
Skimming is a quick way to eliminate parts from consideration, though. There's no point reading the datasheet for a chip that rules itself out on the second paragraph. :)

Im trying to find a source that better explains the meaning of the columns/values labeled Typical, Minimum, Maximum in the electrical characteristic sections of data sheets. What do these values mean? I notice that sometimes all three values are shown, sometimes the Typ. is missing and the other two are shown, sometimes the Max is missing and the other two are shown or sometimes all three are missing. Im having a hard time understanding the true meaning of these three parameters. I asked three different electrical engineers and I got three different explanations.
You say "er-ay-tah', I say 'er-ah-tah', otherwise excellent! 😃 One thing I'm wondering is, when I look at resistor arrays, they are marked as 2%, but how close are the various resistors within the array. Seems to me there should be a 99.99999% match.
Generally the datasheet will specify matching between resistors. If it does not, they are all 2% tolerance and - therefore - there could be a 4% difference between two resistors and the array still (barely) be in spec. Usually though, they will be closer than that.
I generally think that datasheets get a bad rap. They are documents with huge amounts of information in them. Reading and understanding that much information is difficult. What helps me is to know what information I am looking for and why. Then, I make sure I understand what I'm reading before continuing to the next thing. Sitting down and trying to read it like a story is doomed to fail. And yes, there are some (few) totally disastrous datasheets. But I generally think they are in the minority.

Question, why don't you crowdfund your projects to cover costs? By the way, the way you stare into the camera, you amaze me. Nice video.

Just copy the reference design and call it a day. LOL! Btw, what camera are you using? The color looks 1960ish.
Haha yes! It's a GH7. I just like playing with the grade on some videos

You have to read and (mostly) understand every section of the datasheet, otherwise, you'll pay for it the hard way when you have issues in production.
Man it really depends. We're a design shop and not an OEM. We have to be efficient with time. It's nearly always better to make mistakes on the initial design, then fix in the next revision, rather than spend hours and hours trying to get the initial design perfect (which still never happens).

It took me a while to realize he was saying errata.
When I design things, the "absolute maximum" I give a user is higher than the recommended value but lower than the *real* maximum. xD
I generally think that datasheets get a bad rap. They are documents with huge amounts of information in them. Reading and understanding that much information is difficult. What helps me is to know what information I am looking for and why. Then, I make sure I understand what I'm reading before continuing to the next thing.

Haha that footprint tho wtf
he is just reading stuff, very bad explanation and talking style. Why are you not confident to talk facing camera all the time being a youtubeer?
