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
mutually-exclusive active-LOW outputs. Each decoder has
an active-LOW Enable input which can be used as a data in-
put 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.
