CD74HCT139M TI Decoder/Demultiplexer | 16-SOIC | 2-to-4 Line, High-Speed CMOS

Product Overview

The CD74HCT139M 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 where low power dissipation and high noise immunity are required. The device features two independent decoders, each accepting two binary inputs and providing four mutually exclusive active-low outputs. The CD74HCT139M is fabricated with silicon gate technology, ensuring compatibility with LSTTL logic levels while offering the low power consumption of CMOS. It operates over a wide voltage range of 4.5V to 5.5V and is available in a 16-pin SOIC package.
