MC74AC139, MC74ACT139
Dual 1of4
Decoder/Demultiplexer
The MC74AC139/74ACT139 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 MC74AC139/74ACT139 can be used as a function
generator providing four minterms of two variables.
Multifunctional Capability
Two Completely Independent 1
of
4 Decoders
