The SN54LVC02A quadruple 2-input positive-NOR gate is designed for 2.7-V to 3.6-V VCC operation, and the SN74LVC02A quadruple 2-input positive-NOR gate is designed for 1.65-V to 3.6-V VCC operation.
The 'LVC02A devices perform the Boolean function Y = A + B or Y = AB in positive logic.
Inputs can be driven from either 3.3-V or 5-V devices. This feature allows the use of these devices as translators in a mixed 3.3-V/5-V system environment.
