SN74HC27 Triple 3-Input NOR Gates

Texas Instruments SN74HC27 Triple 3-Input NOR Gates contain three independent 3-input NOR gates. Each gate performs the Boolean function Y = A + B + C in positive logic. The Texas Instruments SN74HC27 devices have a wide operating voltage range of 2V to 6V and a broad operating temperature range of -40°C to +85°C.
