DESCRIPTION
The M74HC238 is an high speed CMOS 3 TO 8
LINE DECODER fabricated with silicon gate
C2MOS technology.
If the device is enabled, 3 binary select inputs (A,
B and C) determine which one of outputs will go
high. When enable input G1 is held "Low" or either
G2A or G2B is held "High" decoding function is
inhibited and all the 8 outputs go low. Three
enable inputs are provided to ease cascade
connection
and
application
of
this
address
decoder in memory systems.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
