Overview

HD74AC139/HD74ACT139 Dual 1-of-4 Decoder/Demultiplexer Description The HD74AC139/HD74ACT139 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 HD74AC139/HD74ACT139 can be used as a function generator providing all four minterms of two variables.
