SN74ALS139NS TI Decoder/Demultiplexer | Dual 2-to-4 Line, 4.5-5.5V

Product Overview

The SN74ALS139NS is a dual 2-to-4 line decoder/demultiplexer from Texas Instruments, designed for high-performance memory decoding and data routing applications. It features two independent decoders, each accepting two binary inputs and providing four mutually exclusive active-low outputs. The device is fabricated using advanced Schottky-clamped TTL technology, offering a typical propagation delay of 6 ns and low power consumption of 19 mW per decoder. Operating from a 4.5V to 5.5V supply, it is ideal for 5V logic systems requiring high speed and reliability.
