74F139
Dual 1-of-4 Decoder/Demultiplexer
General Description
Features
The F139 is a high-speed, dual 1-of-4 decoder/demultiplexer. The device has two independent decoders, each
accepting two inputs and providing four mutually exclusive
active LOW outputs. Each decoder has an active LOW
Enable input which can be used as a data input for a 4-output demultiplexer. Each half of the F139 can be used as a
function generator providing all four minterms of two variables.
■ Multifunction capability
■ Two completely independent 1-of-4 decoders

Functional Description
The F139 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 F139 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.
