Supply original NL37WZ17USG, Logic - Buffers, Drivers, Receivers, Transceivers, by ON Semiconductor

Triple Noninverting Schmitt-Trigger Buffer
The NL37WZ17 is a high performance buffer with Schmitt−Trigger inputs operating from a 1.65 to 5.5 V supply.
The NL37WZ17 can be used as a line receiver which will receive slow input signals.
The NL37WZ17 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 NL37WZ17 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.
