74HC 系列解码器/多路复用器，NXP74HC 系列 CMOS 逻辑 IC 的解码器、多路复用器、多路信号分离器和模拟开关系列。 74HC 系列使用硅门 CMOS 技术，实现与 LSTTL 系列类似的工作速度，但标准 CMOS 集成电路功耗降低。### 74HC 系列
General description
The 74HC4066; 74HCT4066 is a quad single pole, single throw analog switch. Each
switch features two input/output terminals nY and nZ and an active HIGH enable input
nE. When nE is LOW, the analog switch isturned off. Inputs include clamp diodes. This
enables the use of current limiting resistors tointerface inputs to voltages in excess of
VCC.
