74LVQ14 Low Voltage Hex Inverter with Schmitt Trigger Input

The LVQ14 contains six inverter gates each with a Schmitt trigger input. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals. In addition, they have a greater noise margin than conventional inverters.

The LVQ14 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.
