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.
