MC74AC132, MC74ACT132 Quad 2Input NAND Schmitt Trigger The MC74AC/74ACT132 contains four 2input NAND gates which are capable of transforming slowly changing input signals into sharply defined, jitterfree output signals. In addition, they have greater noise margin than conventional NAND gates. Each circuit contains a 2input Schmitt trigger. The Schmitt trigger uses positive feedback to effectively speedup slow input transitions, and provide different input threshold voltages for positive and negative-going transitions. This hysteresis between the positivegoing and negativegoing input threshold is determined by resistor ratios and is essentially insensitive to temperature and supply voltage variations.
