The SN74LVC00AD is a quadruple 2-input Positive-NAND Gate designed for 1.65 to 3.6V VCC operation. The device perform the Boolean function Y = (A x B)\ or Y = A\ + B\ in positive logic. Inputs can be driven from either 3.3V or 5V devices. This feature allows the use of these devices as translators in a mixed 3.3V/5V system environment.
