Digital isolator tolerant ADuM1400

Category: Datasheet/Specs
Product Number: ADuM1400

Hi All

I have a question about the ADuM1400 digital isolator.

When the power supply is 0V,

If I apply voltage 0-5V to input pin , will it  break because it is over rated?
Or will the input not break due to the tolerant function?

I am concerned that it will break when the power off and there is input from the connector.

Thank you in advance.
