1−of−4 decoder/demultiplexer. The device has two
independent decoders, each of which accepts two binary
weighted inputs (A
exclusive active−LOW outputs (O
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.
The MC74AC139/74ACT139 is a high−speed dual
