Number Package Description
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
positive-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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.
