MC74HCT138A

1-of-8 Decoder/

Demultiplexer with LSTTL

Compatible Inputs

High−Performance Silicon−Gate CMOS

www.onsemi.com

The MC74HCT138A is identical in pinout to the LS138. The

HCT138A may be used as a level converter for interfacing TTL or

NMOS outputs to High Speed CMOS inputs.

The HCT138A decodes a three−bit Address to one−of−eight

active−lot outputs. This device features three Chip Select inputs, two

active−low and one active−high 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; one of the Chip Selects is used as a data input while the

other Chip Selects are held in their active states.
