The first IC of the 7400 series is of course, the 74xx00. I use the 74HC00 version in this video. It is a quad (there are 4) 2 input NAND gates in it. The NAND gate is the inverted version of the AND gate. Instead of the output being low unless all inputs are high, as is the case of the AND gate, the NAND gate has a high output unless all inputs are high, in which case it is set low.
