TMUX6201: Signal input while Vcc is not supplied

? ??

Part Number: TMUX6201

Tool/software:

While VDD is not supplied(VDD=VSS), if high level AC signal is input to S or D pin,, is this device damaged? Is there any care or protection method?

Hello,

I supposed that depends on the actual voltage and current of that signal but either way you'd be violating the datasheet specs and using the device outside of it's intended functionality so there really isn't a definitive way to know what the outcome would be. I wouldn't recommend using the device like that.
Is there no way to avoid that event from occurring? If not, you'll need a device with powered off protection

Thanks,
Rami

Thank you.

Is there any example of "powered off protection"? such as some devices, circuit structure, and so on.

Here is a list: ti.com/switches-multiplexers/analog/products.html#2192=Powered-off protection

The maximum I/O voltage when the device is powered off is listed in either the absolute maximum ratings or as test condition for the the off-state leakage current in the electrical characteristics.
