74AC139SCX - Fairchild Function Overview

General Description
The AC/ACT139 is a high-speed, dual 1-of-4 decoder/demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutually exclusive active-LOW outputs. Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the AC/ACT139 can be used as a function generator providing all four minterms of two variables.
Features
■ ICC reduced by 50%
■ Multifunction capability
■ Two completely independent 1-of-4 decoders
■ Active LOW mutually exclusive outputs
■ Outputs source/sink 24 mA
■ ACT139 has TTL-compatible inputs
