SN74HC139ANSR TI Decoder/Demultiplexer | 16-SO | Dual 2-to-4, 2V-6V

Product Overview

The SN74HC139ANSR is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for high-speed CMOS logic applications. It features two independent decoders, each accepting two binary inputs and providing four mutually exclusive active-low outputs. The device is ideal for memory decoding, data routing, and general-purpose logic functions. Housed in a 16-pin SO package, it operates over a wide voltage range of 2V to 6V, making it suitable for battery-powered and industrial systems.
