CD74AC139E TI Decoder/Demultiplexer | 16-PDIP | Dual 2-to-4, 1.5V-5.5V

Product Overview

The CD74AC139E from Texas Instruments is a high-speed dual 2-to-4 line decoder/demultiplexer fabricated with advanced AC CMOS technology. It operates over a wide voltage range of 1.5V to 5.5V, making it suitable for battery-powered and low-voltage applications. The device features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0-Y3). It is ideal for memory decoding, data routing, and demultiplexing in digital systems. The 16-pin PDIP package ensures easy integration into through-hole PCB designs.
