Revised December 1999 74LVX14 Low Voltage Hex Inverter with Schmitt Trigger Input General Description Features The LVX14 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. Input voltage level translation from 5V to 3V Ideal for low power/low noise 3.3V applications Guaranteed simultaneous switching noise level and dynamic threshold performance The LVX14 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 systems to 3V systems.

The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table will define the conditions for actual device operation.
