MC74AC132MEL集成电路（IC）的门反相器规格书PDF中文资料

MC74AC132MEL属于集成电路（IC）的门反相器。由安森美半导体公司制造生产的MC74AC132MEL门和反相器逻辑栅极和逆变器系列中的产品对单个逻辑信号执行基本逻辑运算（例如 AND、NOT、OR 等）。与触发器不同，它们不能够存储信息，不会对提供给其输入的信号立即做出响应。虽然早就被集成电路实施形式所取代，以用于实现复杂功能，但分立栅极仍可在仅需要非常简单逻辑功能的情况下使用。

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.
