74F139 Dual 1-of-4 Decoder/Demultiplexer
74F139
Dual 1-of-4 Decoder/Demultiplexer
General Description
The F139 is a high-speed, dual 1-of-4 decoder/demulti-
plexer. 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.
Features
■ Multifunction capability
■ Two completely independent 1-of-4 decoders
■ Active LOW mutually exclusive outputs
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

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 (A
0
–A
1
) and pro-
vides four mutually exclusive active LOW Outputs (O
0
–O
3
).
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.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
Note 1: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
