The AND gate has two inputs A and B. The output of the gate, A.B, depends on the two inputs according to the truth table at the right. The AND gate has a “1” output only when both A and B are 1.

Texas Instruments’ 5400 and 7400 TTL quad 2-input NAND gate has been in continuous production since 1964 and is the progenitor of what is probably the most numerous breed of integrated circuits, ...

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.

Computers use electrical circuits which have two states – on or off. This can also be represented as 1 or 0 or True and False. Logic gates take an input of True or False and give an output of ...
