Certainly not us, it’s as though they have disappeared ... quantity equivalent coming in at about 30 cents. A quad 2-input NAND gate is hardly the most exciting or exotic of components unless ...

An AND gate usually has two inputs. AND tells us that both Input A AND Input B have to be 1 (or ON) in order for the output to be 1. Otherwise the output is 0.

A logic gate is a series of transistors connected together to give one or more outputs, each output being based on the input or combination of inputs supplied to it.
