Overview
The MC74ACT132DR2G, produced by onsemi, is a Quad 2-Input NAND Schmitt Trigger integrated circuit. This device contains four 2-input NAND gates that are designed to transform slowly changing input signals into sharply defined, jitter-free output signals. It features Schmitt trigger inputs, which use positive feedback to speed up slow input transitions and provide different input threshold voltages for positive and negative-going transitions. This hysteresis is essentially insensitive to temperature and supply voltage variations, offering greater noise margin compared to conventional NAND gates.
