74LVX14 Low Voltage Hex Inverter with Schmitt Trigger Input
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 in to sharply defined, jitte r-free output signals. In additio n, they have a greater no ise margin
than conventional inverters.
The LVX14 has hysteresis between the positi ve-going a nd
negative-going input thresholds (typically 1.0V) which is
determined internall y by transistor ratios an d 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
■ 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

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
