SN74LS27DR TI Triple 3-Input NOR Gate | 14-SOIC | 4.75V-5.25V, TTL

Product Overview

The SN74LS27DR from Texas Instruments is a triple 3-input positive-NOR gate integrated circuit. It belongs to the 74LS family of low-power Schottky TTL logic devices. The device is designed to operate from a single 5V power supply and provides the logic function Y = A + B + C (inverted OR). Each gate performs the Boolean function Y = (A + B + C)' in positive logic. The SN74LS27DR is offered in a 14-pin SOIC package, making it suitable for surface-mount applications. It features typical propagation delay of 15 ns and low power consumption of 2 mW per gate.
