DESCRIPTION

The 74AC138 is an advanced high-speed CMOS

3 TO 8 LINE DECODER (INVERTING) fabricated

with sub-micron silicon gate and double-layer

metal wiring C2MOS tecnology.

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 to high.

Tree enable inputs are provided to ease cascade

connection and application of address decoders

for memory systems.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
