If you look up a data sheet for any 7483 variant, it is immediately notable: the first lines are something like "4-bit binary full adder" and the description says "…accept two 4-bit binary words" If you skip to the next paragraph, you’ll see they are onto transistors. Ideally the author could show a data sheet, but there may be reasons they can’t.

I found the material that followed to be a clear exposition of the fundamentals – this is as somebody who has tried to learn electronics over the years but nothing ever stuck. This did a better job than anything else at a pace that is about right for me.

But YMMV and I personally relish being in a room full of people who are smarter than me.
