14 High−Performance Silicon−Gate CMOS MC74AC132, MC74ACT132
The MC74AC/74ACT132 contains four 2−input NAND gates
which are capable of transforming slowly changing input signals into
sharply defined, jitter−free output signals. In addition, they have
greater noise margin than conventional NAND gates.
Each circuit contains a 2−input Schmitt trigger. The Schmitt trigger
uses positive feedback to effectively speed−up slow input transitions,
and provide different input threshold voltages for positive and
negative-going transitions. This hysteresis between the positive−going
and negative−going input threshold is determined by resistor ratios
and is essentially insensitive to temperature and supply voltage
variations. 14 SOIC−14
