The AND gate is a basic digital that implements - it behaves according to the to the right. A HIGH output (1) results only if both the inputs to the AND gate are HIGH (1). If neither or only one input to the AND gate is HIGH, a LOW output results. In another sense, the function of AND effectively finds the between two binary digits, just as the function finds the . Therefore, the output is always 0 except when all the inputs are 1.

There are three symbols for AND gates: the American ( or 'military') symbol and the ('European' or 'rectangular') symbol, as well as the deprecated symbol. For more information see .

An AND gate is usually designed using N-channel (pictured) or P-channel . The digital inputs a and b cause the output F to have the same result as the AND function.

If no specific AND gates are available, one can be made from or gates, because NAND and NOR gates are considered the "universal gates," meaning that they can be used to make all the others.
