NAND Gate
The NAND gate (NOT AND) is a logic gate which produces an low output only if all its inputs are high; thus its output is complement to that of the AND gate. A low (0) output results only if both the inputs to the gate are high (1); if one or both inputs are low (0), a high (1) output results.
