AND gate truth table
Input		Output
A	B	A AND B
0	0	0
0	1	0
1	0	0
1	1	1

The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – AND gate behaves according to the truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If not all of the inputs to the AND gate are HIGH, a LOW output results. The function can be extended to any number of inputs.
