NAND
What is a NAND?
A Not AND is a combination of the NOT and AND logic gates. In boolean logic the truth table looks like this:

A | B | A NAND B

--+---+---------

F | F | T

F | T | T

T | F | T

T | T | F

Typically the circuits that make up a NAND are



The above example is from the IC7400 and here is the Quad NADN IC7400
