74LCX14 Low voltage CMOS HEX SCHMITT inverter with 5V tolerant inputs

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
