The LCX14 contains six inverter gates each with a
Schmitt trigger input. They are capable of transforming
slowly changing input signals into sharply defined, jitterfree output signals. In addition, they have a greater noise
margin than conventional inverters.
The LCX14 has hysteresis between the positive-going
and negative-going input thresholds (typically 1.0V)
which is determined internally by transistor ratios and is
essentially insensitive to temperature and supply voltage
variations.
The inputs tolerate voltages up to 7V allowing the interface of 5V, 3V and 2.5V systems.
The 74LCX14 is fabricated with advanced CMOS technology to achieve high speed operation while maintaining CMOS low power dissipation.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
