Dual 1-of-4 Decoder/Demultiplexer
General Description
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. Each half of the AC/
ACT139 can be used as a function generator providing all
four minterms of two variables.
