74LVX132
Low Voltage Quad 2-Input NAND Schmitt Trigger
General Description
The LVX132 contains four 2-input NAND Schmitt Trigger
Gates. The pin configuration and function are the same as
the LVX00 but the inputs have hysteresis between the pos-
itive-going and negative-going input thresholds, which are
capable of transforming slowly changing input signals into
sharply defined, jitter-free output signals, thus providing
greater noise margins than conventional gates.
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

Note 1: 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 2: Unused inputs must be held HIGH or LOW. They may not float.
