SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

J SUFFIX

CERAMIC PACKAGE

CASE 620–10

The MC54/74HC139A is identical in pinout to the LS139. The device

inputs are compatible with standard CMOS outputs; with pullup resistors,

they are compatible with LSTTL outputs.

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.
