SN74LS02N TI Logic Gates | 14-PDIP | Quad 2-Input NOR Gate, 4.75V-5.25V

Product Overview

The SN74LS02N is a quad 2-input positive-NOR gate from Texas Instruments, part of the 74LS family of low-power Schottky logic devices. It integrates four independent NOR gates in a single 14-pin PDIP package, providing high-speed logic operations with low power consumption. Each gate performs the Boolean function Y = A + B in positive logic, making it suitable for a wide range of digital logic applications. The device operates from a standard 5V supply and features typical propagation delays of 10 ns, with a maximum input current of 20 µA. Its robust design ensures reliable performance in industrial and commercial environments.
