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.
