NL37WZ14
Triple Schmitt−Trigger
Inverter
The NL37WZ14 is a high performance triple inverter with
Schmitt−Trigger inputs operating from a 1.65 to 5.5 V supply.
Pin configuration and function are the same as the NL37WZ04, but
the inputs have hysteresis, and with its Schmitt trigger function, the
NL37WZ14 can be used as a line receiver which will receive slow
input signals. The NL37WZ14 is capable of transforming slowly
changing input signals into sharply defined, jitter−free output signals.
In addition, it has a greater noise margin than conventional inverters.
The NL37WZ14 has hysteresis between the positive−going and the
negative−going input thresholds (typically 1.0 V) which is determined
internally by transistor ratios and is essentially insensitive to
temperature and supply voltage variations.
