SN74AS21NS TI Dual 4-Input AND Gate | 4.5V-5.5V, 8ns Propagation Delay

Product Overview

The SN74AS21NS is a dual 4-input positive-AND gate from Texas Instruments' advanced Schottky (AS) logic family. It integrates two independent 4-input AND gates in a single 14-pin SO package, providing high-speed logic operations with typical propagation delays of 8 ns. Operating from a 4.5V to 5.5V supply, this device is designed for high-performance digital systems requiring fast switching and low power consumption. The SN74AS21NS is ideal for applications in computing, telecommunications, and industrial control where reliable AND logic functions are essential.
