Dave takes you on a complete walk-through of a typical (7400) digital logic datasheet and explains all the specifications and information.

I never paid any attention to the "Typical Applications" notes before...

That was funny.   :-+

The worst revision of datasheet I have ever seen (read got caught by) was on supply voltage. In the older datasheet I originally had (at work we use common components and store datasheets on a local server) happily said the chip worked down to 3V - Goody, I was designing with 3.3V. The new datasheet changed this to 3.7V. Fortunatly, I spotted this before I had the PCB laid out.
