MC74AC14数据手册集成电路（IC）的门反相器规格书PDF

描述 Description

The MC74AC14/74ACT14 contains six logic inverters which accept standardCMOS Input signals (TTL levels for MC74ACT14) and provide standard CMOSoutput levels. They are capable of transforming slowly changing input signals intosharply defined, jitter-free output signals. In addition, they have a greater noisemargin then conventional inverters. The MC74AC14/74ACT14 has hysteresis between the positive-going andnegative-going input thresholds (typically 1.0 V) which is determined internally bytransistor ratios and is essentially insensitive to temperature and supply voltagevariations.

特性 Features

• Schmitt Trigger Inputs
• Outputs Source/Sink 24 mA
• ACT14 Has TTL Compatible Inputs
• Pb-Free Packages are Available

简介

MC74AC14属于集成电路（IC）的门反相器。由制造生产的MC74AC14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。
