MC74HC238A
1-of-8 Decoder/
Demultiplexer
HighâPerformance SiliconâGate 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 threeâbit Address to oneâofâeight
activeâhigh outputs. This device features three Chip Select inputs, two
activeâlow and one activeâhigh to facilitate the demultiplexing,
cascading, and chipâselecting 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.
