Analog Switches, Multiplexers, Demultiplexers FAQ

How does the enable input function?

The enable input (E) is active LOW. When E is HIGH, all switches are turned off regardless of the state of the address inputs S0 through S3.

What is the purpose of the input clamp diodes?

The inputs include clamp diodes that allow the use of current limiting resistors to interface inputs to voltages in excess of VCC without damaging the device.

Can the Yn and Z terminals be used interchangeably?

Yes, the Yn and Z terminals are bidirectional. They can function as either inputs or outputs depending on the direction of signal flow in the application.
