DESCRIPTION

The 74LCX138 is a low voltage CMOS 3 TO 8

LINE DECODER (INVERTING) fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS technology. It is ideal for low power

and high speed 3.3V applications; it can be

interfaced to 5V signal environment for inputs.

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.

Three enable inputs are provided to ease cascade

connection and application of address decoders

for memory systems.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
