DESCRIPTION

The M74HC138 is an high speed CMOS 3 TO 8

LINE DECODER fabricated with silicon gate

C 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.
