MC74AC139 General Description
The MC74AC139/74ACT139 is a highspeed, dual 1of4 decoder/demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutuallyexclusive activeLOW outputs. Each decoder has an activeLOW Enable input which can be used as a data input for a 4output demultiplexer. Each half of the MC74AC139/74ACT139 can be used as a function generator providing four minterms of two variables.
