Overview
1-of-8 Decoder/ Demultiplexer High−Performance Silicon−Gate CMOS MC74HC138A The MC74HC138A is identical in pinout to the LS138.
The device inputs are compatible with standard CMOS outputs; with pullup resistors, they are compatible with LSTTL outputs.
The HC138A decodes a three−bit Address to one−of−eight active−low 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.
Features  Output Drive Capability: 10 LSTTL Loads  Outputs Directly Interface to CMOS, NMOS and TTL  Operating Voltage Range: 2.
0 to 6.
0 V  Low Input Current: 1.
0 mA  High Noise Immunity Characteristic of CMOS Devices  In Compliance with the Requirements Defined by JEDEC Standard No.
7 A  ...
