74系列逻辑芯片/74HC4066PW
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.
