Product Summary

The 74hc139 is a dual 2-to-4 line decoder/demultiplexer. The 74hc139 is a high-speed Si-gate CMOS device and are pin compatible with low power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard no. 7A. This 74hc139 has two independent decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four mutually exclusive active LOW outputs (nY0 to nY3).
