Functional Description
The F139 is a high-speed dual 1-of-4 decoder/demulti-
plexer. The device has two independent decoders, each of
which accepts two binary weighted inputs (A0–A1) and pro-
vides 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 F139 generates all four minterms of two
variables. These four minterms are useful in some applica-
tions, replacing multiple gate functions as shown in
Figure 1, and thereby reducing the number of packages
required in a logic network.
