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

FUNCTIONAL DESCRIPTION
The MC74AC139/74ACT139 is a high–speed dual
1–of–4 decoder/demultiplexer. The device has two
independent decoders, each of which accepts two binary
weighted inputs (A
) and provides four mutually
0–A1
exclusive active–LOW outputs (O0–O3). Each decoder has
an active–LOW enable (E). When E is HIGH all outputs are
forced HIGH. The enable can be used as the data input for
a 4–output demultiplexer application. Each half of the
MC74AC139/74ACT139 generates all four minterms of
two variables. These four minterms are useful in some
applications, replacing multiple gate functions as shown in
Figure 4, and thereby reducing the number of packages
required in a logic network.
