SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

N SUFFIX

PLASTIC PACKAGE

CASE 648–08

The MC74HC137 is identical in pinout to the LS137. The device inputs are

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

compatible with LSTTL outputs.

The HC137 decodes a three–bit Address to one–of–eight active–low

outputs. The device has a transparent latch for storage of the Address. Two

Chip Selects, one active–low and one active–high, are provided to facilitate

the demultiplexing, cascading, and chip–selecting functions.

The demultiplexing function is accomplished by using the Address inputs

to select the desired device output, and then by using one of the Chip

Selects as a data input while holding the other one active.
