M74HC14数据手册集成电路（IC）的信号开关多路复用器解码器规格书PDF

描述 Description

The M74HC14 is a high speed CMOS hex Schmitt inverter fabricated with silicon gate C2MOS technology. Pin configuration and functions are the same as those of the M74HC04 but all inputs have a 20 % VCC hysteresis level.
This, together with the Schmitt trigger function, allows the device to be used on line receivers with slow rise/fall input signals.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.

简介

M74HC14属于集成电路（IC）的信号开关多路复用器解码器。由制造生产的M74HC14信号开关，多路复用器，解码器逻辑型信号开关、多路复用器和编码器 IC 可用于对以数字格式表示数据的电信号进行路由和选择。这些器件与设计用于模拟信号的类似产品有所不同，它们保留的信息表示为两个电状态之一，而不是两个外部界限内的无穷变化量。
