SN74LS02NS TI Quad 2-Input NOR Gate | 14-SO | 4.75V-5.25V, TTL

Product Overview

The SN74LS02NS is a high-performance Quad 2-Input Positive-NOR Gate from Texas Instruments, housed in a 14-pin SO package. It belongs to the 74LS family of low-power Schottky TTL logic devices, offering a balance of speed and power consumption. Each gate performs the logical NOR function: Y = A + B (inverted OR). The device operates from a standard 5V supply and is designed for use in a wide range of digital logic applications.
