CD74ACT238E TI Decoder/Demultiplexer | 16-PDIP | 3-to-8, 4.5V-5.5V

Product Overview

The CD74ACT238E from Texas Instruments is a high-speed 3-to-8 line decoder/demultiplexer fabricated with advanced CMOS technology. It is designed for memory decoding and data routing applications requiring low power dissipation and high noise immunity. The device features three binary select inputs (A0, A1, A2) and an active-low enable input (G), providing eight mutually exclusive active-high outputs (Y0–Y7). It operates over a supply voltage range of 4.5V to 5.5V, making it ideal for 5V digital systems. The 16-pin PDIP package ensures easy integration into through-hole PCB designs.
