Functional Description
The VHC139 is a high-speed dual 2-to-4 decoder/demulti-
plexer. The device has two independent decoders, each of
which accepts two binary weighted inputs (A
vides four mutually exclusive active-LOW outputs (O
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 VHC139 generates all four minterms of
two variables. These four minterms are useful in some
applications, replacing multiple gate functions as shown in
Figure 1 , and thereby reducing the number of packages
required in a logic network.
