DESCRIPTION
The 74LCX14 is a low voltage CMOS HEX
SCHMITT INVERTER 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

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.
