I like maxim's documentation because it's complete, and quite conservative, and the components they make seem to always conform to specs, unline some other manufacturers. > In some cases, I've even resorted to measuring on actual > components that I happen to have laying around ... > Ouch!

Nominal is fine, IMO. Nominal is a manufacturer's way of saying "it's how it should look, but we can't get it that exact".
