MC74AC132MEL

四2输入与非施密特触发器 Quad 2−Input NAND Schmitt Trigger

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.
