MC74HC139A

Dual 1−of−4 Decoder/

Demultiplexer

High−Performance Silicon−Gate CMOS

The MC74HC139A is identical in pinout to the LS139. The device

inputs are compatible with standard CMOS outputs; with pull−up

resistors, they are compatible with LSTTL outputs.

MARKING

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.
