IN74HCT139A

DUAL 1-OF-4 DECODER/DEMULTIPLEXER

High-Performance Silicon-Gate CMOS

The IN74HCT139A is identical in pinout to the LS/ALS139.

The IN74HCT139A may be used as a level converter for

interfacing TTL or NMOS outputs to High Speed CMOS inputs.

This device consists of two independent 1-of-4 decoders,

each of which decodes a two-bit Address to one-of-four active-

low outputs. Active-low Selects are provided to facilitate the

demultiplexing and cascading functions. The demultiplexing

function is accomplished by using the Address inputs to select

the desired device output, and utilizing the Select as a data input.

• TTL/NMOS Compatible Input Levels

• Outputs Directly Interface to CMOS, NMOS, and TTL

• Operating Voltage Range: 4.5 to 5.5 V

• Low Input Current: 1.0 µA
