Texas Instruments CD74AC02 Quad 2-Input NOR Gates
Texas Instruments CD74AC02 Quad 2-Input NOR Gates contain four independent 2-input NOR gates that perform the Boolean function Y = A • B or Y = A + B in positive logic. These devices have a 1.5V to 5.5V supply voltage range and offer balanced noise immunity at 30% of the supply voltage. The Texas Instruments CD74AC02 devices have a ±24mA output drive current that can fanout to 15 F devices.
