Details of the 7400 series TTL integrated circuits that were widely used for logic / digital circuit designs.
74 and 54 Series ICs all have a code on the top of the carrier body. This can be printed (usually in white) or etched. It consists of a "core" code which identifies.

This is often supplemented by manufacturer's prefixes and suffixes which give information about the manufacturer and the carrier's physical form. The best answers are voted up and rise to the top. Well, if you have already have them on-hand, there is no reason not to do the labs and get a good feel for what they do and how they operate. In addition, I was convinced that learning to use discrete logic ICs is a good preparatory step before starting in on programmable logic devices. It's probably more important to keep your interest up and do things you consider fun than to follow a perceived path.
At large quantities, these logic ICs are dirt cheap and cost a fraction of some PWM controller or whatever, and you can tweak the circuit so well that you know exactly what's going on.

I started in on 7400 series by following the labs in the "Art of Electronics" lab manual which includes labs with these chips.
