NL37WZ17 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.

CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC. CPD is used to determine the no−load dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
