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 C
2
MOS 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.
