The NAND gate (negative-AND) is a logic gate which produces an output which is false only if all its inputs are true thus its output is a 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.
INPUT | OUTPUT | |
---|---|---|
A | B | A NAND B (Q) |
0 | 0 | 1 |
0 | 1 | 1 |
1 | 0 | 1 |
1 | 1 | 0 |
