74LVX14
Low Voltage Hex Inverter with Schmitt Trigger Input
General Description
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 out-
put signals. In addition, they have a greater noise margin
than conventional inverters.
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.
Features
s
Input voltage level translation from 5V to 3V
s
Ideal for low power/low noise 3.3V applications
s
Guaranteed simultaneous switching noise level and
dynamic threshold performance

Recommended Operating
Conditions
(Note 3)
Note 2: The "Absolute Maximum Ratings" are those values beyond which
the safety of the device cannot be guaranteed. 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.
Note 3: Unused inputs must be held HIGH or LOW. They may not float.
