MC74VHC14中文资料带施密特触发器输入的六路逆变器数据手册ONSEMI规格书

描述 Description

The MC74VHC14 is an advanced high speed CMOS Schmitt inverter fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. Pin configuration and function are the same as the MC74VHC04, but the inputs have hysteresis and, with its Schmitt trigger function, the VHC14 can be used as a line receiver which will receive slow input signals. The internal circuit is composed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs tolerate voltages up to 7V, allowing the interface of 5V systems to 3V systems.

简介

MC74VHC14属于集成电路（IC）的门反相器。由制造生产的MC74VHC14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。
