LOGIC DIAGRAM
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
(A0–A1) and provides four mutually 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 a, and thereby reducing the
number of packages required in a logic network.
