FUNCTIONAL DESCRIPTION
The LS139 is a high speed dual 1-of-4 decoder/
demultiplexer fabricated with the Schottky barrier diode
process. The device has two independent decoders, each of
which accept two binary weighted inputs (A0, A1) and
provide four mutually exclusive active LOW outputs
(O0O3). 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 LS139 generates all four minterms of two
variables. These four minterms are useful in some
applications, replacing multiple gate functions as shown in
Fig. a, and thereby reducing the number of packages
required in a logic network.
