DESCRIPTION
The M74HC138 is an high speed CMOS 3 TO 8
LINE DECODER fabricated with silicon gate
C
2
MOS technology.
If the device is enabled, 3 binary select inputs (A,
B, and C) determine which one of the outputs will
go low. If enable input G1 is held low or either G2A
or G2B is held high, the decoding function is
inhibited and all the 8 outputs go high. Three
enable inputs are provided to ease cascade
connection and application of address decoders
for memory systems.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
