DESCRIPTION

The 74LCX14 is a low voltage CMOS HEX

SCHMITT INVERTER fabricated with sub-micron

technology. It is ideal for low power and high

speed 3.3V applications. It can be interfaced to 5V

signal environment for inputs

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

Pin configuration and function are the same as

those of

the 74LCX04 but the 74LCX14 has

hysteresis between the positive and negative

input threshold typically of 0.8V.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input signals.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
