Dual 1-of-4 Decoder Demultiplexer
General Description
The ’F139 is a high-speed dual 1-of-4 decoder demultiplex-
er The device has two independent decoders each accept-
ing two inputs and providing four mutually exclusive active
LOW outputs Each decoder has an active LOW Enable in-
put which can be used as a data input for a 4-output demul-
tiplexer Each half of the ’F139 can be used as a function
generator providing all four minterms of two variables
Features
Y Multifunction capability
Y Two completely independent 1-of-4 decoders

Functional Description
The ’F139 is a high-speed dual 1-of-4 decoder demultiplex-
er 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
