The SN54LVC00A quadruple 2-input positive-NAND gate is designed for 2.7V to 3.6V VCC operation, and the SN74LVC00A quadruple 2-input positive-NAND gate is designed for 1.65V to 3.6V VCC operation. The SNx4LVC00A devices perform the Boolean function Y = A • 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.
