To all our customers
Regarding the change of names mentioned in the document, such as Hitachi
Electric and Hitachi XX, to Renesas Technology Corp.
The semiconductor operations of Mitsubishi Electric and Hitachi were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Hitachi, Hitachi, Ltd., Hitachi Semiconductors, and other Hitachi brand
names are mentioned in the document, these names have in fact all been changed to Renesas
Technology Corp. Thank you for your understanding. Except for our corporate trademark, logo and
corporate statement, no changes whatsoever have been made to the contents of the document, and
these changes do not constitute any alteration to the contents of the document itself.

HD74AC139/HD74ACT139
Dual 1-of-4 Decoder/Demultiplexer
ADE-205-369 (Z)
1st. Edition
Sep. 2000
Description
The HD74AC139/HD74ACT139 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 HD74AC139/HD74ACT139 can be used as a function generator providing
all four minterms of two variables.

Functional Description
The HD74AC139/HD74ACT139 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 to A1) and provides four
mutually exclusive active-Low outputs (O0 to 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 HD74AC139/HD74ACT139 generates all four minterms of two variables.
These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure
a, and thereby reducing the number of packages required in a logic network.
