MC74HC238A

1-of-8 Decoder/

Demultiplexer

High−Performance Silicon−Gate CMOS

The MC74HC238A is identical in pinout to the LS238. The device

inputs are compatible with standard CMOS outputs; with pullup

resistors, they are compatible with LSTTL outputs.

The HC238A decodes a three−bit Address to one−of−eight

active−high 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.
