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.
