SN74HC139D TI Decoder/Demultiplexer | 16-SOIC | Dual 2-to-4, 2V to 6V

Product Overview

The SN74HC139D is a high-speed dual 2-to-4 line decoder/demultiplexer from Texas Instruments, fabricated using advanced silicon-gate CMOS technology. It is designed for applications requiring low power consumption 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). The SN74HC139D operates over a wide supply voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems. It is offered in a compact 16-SOIC package, ideal for space-constrained designs.
