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 MC74AC139/74ACT139 can be used as a function

generator providing four minterms of two variables.
