MM74HC14集成电路（IC）的门反相器规格书PDF中文资料

MM74HC14属于集成电路（IC）的门反相器。由安森美半导体制造生产的MM74HC14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。

特性 Features

■ Typical propagation delay: 13ns

■ Wide power supply range: 2V–6V

■ Low quiescent current: 20µA maximum (74HC Series)

■ Low input current: 1µA maximum

■ Fanout of 10 LS-TTL loads

■ Typical hysteresis voltage: 0.9V at VCC = 4.5V

General Description

The MM74HC14 utilizes advanced silicon-gate CMOS

technology to achieve the low power dissipation and

high noise immunity of standard CMOS, as well as the

capability to drive 10 LS-TTL loads.

The 74HC logic family is functionally and pinout compatible with the standard 74LS logic family. All inputs are

protected from damage due to static discharge by internal diode clamps to VCC and ground.
