Dual 1-of-4
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 Active LOW Mutually Exclusive Outputs Outputs Source/Sink 24 mA ′ACT139 Has TTL Compatible Inputs
