I'm still just beginning my adventure into electronics and IC chips and datasheets have me confused so I'm going to ask a series of beginner questions will help me and hopefully others as well.
There are many different IC and IC manufactures out there. Specifically for the 74 line, are these chips standard across the different manufacturers? If not, what are generally the differences between them? Will it matter if I mix and match different ICs from different manufactures?
Datasheets, for some reason these tend to be horribly thought out and rather difficult for a beginner like me to decipher (I've noticed TI is notorious for this, giving abbreviations to all their pins without any explanation. What the heck is OE?). Is there a company (assuming that all chips are standard between different manufacturers) that provides clear and concise datasheets for all of the 74 IC chip line?
