I2C function when unpowered device

Thread Summary

The user asked if an unpowered LTC2495 can damage the I2C bus. The final answer confirms that unpowering the LTC2495 while the I2C bus is active can cause permanent damage due to exceeding the device's absolute maximum ratings, which are referenced to VCC. The engineer advised against unpowering the LTC2495 to maintain bus integrity and device reliability.

The text on p14. In the specification confusing me.
It states 
"The VCC power should not be removed from the device
when the I2C bus is active to avoid loading the I2C bus
lines through the internal ESD protection diodes."

Can you confirm that an unpowerd LTC2495 do not destroy the I2C bus ?

I still want access other components over I2C when LTC2495 is turned off.
