SN74AHC139NSR TI Decoder/Demux | 16-SO | 2-to-4, 2V-5.5V

Product Overview

The SN74AHC139NSR is a high-speed dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for 2-V to 5.5-V VCC operation. It is fabricated using advanced AHC technology, offering 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). It is ideal for memory decoding, data routing, and general-purpose logic applications.
