CD74ACT138E TI Decoder/Demultiplexer | 16-PDIP | 3-to-8 Line, 4.5V-5.5V

Product Overview

The CD74ACT138E 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 enable inputs (G1, G2A, G2B) for easy expansion and three binary select inputs (A, B, C) to select one of eight outputs. The outputs are active low, making it ideal for use with memory chips and other logic families. Operating from a 4.5V to 5.5V supply, the CD74ACT138E is offered in a 16-pin PDIP package, suitable for through-hole mounting in industrial and consumer electronics.
