描述 Description

The MC74AC/74ACT132 contains four 2-input NAND gates which are capableof transforming slowly changing input signals into sharply defined, jitter-free outputsignals. In addition, they have greater noise margin than conventional NAND gates. Each circuit contains a 2-input Schmitt trigger. The Schmitt trigger uses positivefeedback to effectively speed-up slow input transitions, and provide different inputthreshold voltages for positive and negative-going transitions. This hysteresisbetween the positive-going and negative-going input threshold is determined byresistor ratios and is essentially insensitive to temperature and supply voltagevariations.

簡介

MC74ACT132屬于集成電路（IC）的門反相器。由制造生產(chǎn)的MC74ACT132門和反相器邏輯柵極和逆變器系列中的產(chǎn)品對(duì)單個(gè)邏輯信號(hào)執(zhí)行基本邏輯運(yùn)算（例如 AND、NOT、OR 等）。與觸發(fā)器不同，它們不能夠存儲(chǔ)信息，不會(huì)對(duì)提供給其輸入的信號(hào)立即做出響應(yīng)。雖然早就被集成電路實(shí)施形式所取代，以用于實(shí)現(xiàn)復(fù)雜功能，但分立柵極仍可在僅需要非常簡單邏輯功能的情況下使用。
