DESCRIPTION

The 74LCX05 is a low voltage CMOS OPEN

DRAIN

HEX

INVERTER

fabricated

with

sub-micron silicon gate and double-layer metal

and high speed 3.3V applications. It can be

interfaced to 5V signal environment for inputs.

The internal circuit is composed of 3 stages

including buffer output, which provides high noise

immunity and stable output.

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.
