FACT DATA
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.
