CD74HC139MT TI Decoder/Demultiplexer | 16-SOIC | 2-to-4 Line, High-Speed CMOS

Product Overview

The CD74HC139MT from Texas Instruments is a high-speed CMOS dual 2-to-4 line decoder/demultiplexer. It is designed for memory decoding and data routing 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 CD74HC139MT is fabricated with silicon gate technology, ensuring balanced propagation delays and high drive capability. It operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems. The 16-SOIC package offers a compact footprint for space-constrained designs.
