TS5A3359: Analog signal path and digital pins isolation?

The control pins are high-impedance CMOS inputs, so they are isolated.

When connecting the device as in the schematic (with both control inputs low), all I/Os are disconnected. This is probably not what you want.

Hello

In addition to what clemens said. Yes the analog pins and digital control pins are isolated from each other. In addition they can share the same ground.

The ground pin is the refernce for the analog on control pins.

Finally,  you will need pull up or pull down resistors on the control pins input to determine what state you want the mux to be in  by default.
