CD74ACT139M TI Decoder/Demultiplexer | 16-SOIC | Dual 2-to-4 Line

Product Overview

The CD74ACT139M from Texas Instruments is a high-speed dual 2-to-4 line decoder/demultiplexer fabricated with advanced CMOS logic. It is designed for memory decoding and data routing applications requiring low power dissipation and high noise immunity. The device features two independent decoders, each accepting two binary inputs (A0, A1) and providing four mutually exclusive active-low outputs (Y0–Y3). An active-low enable input (G) controls each decoder. The CD74ACT139M operates over a wide voltage range of 4.5V to 5.5V and is offered in a compact 16-SOIC package, making it suitable for space-constrained designs.
