ADG1411 behavior when powered OFF

Hello, I would like to know if it's safe to have a signal input when ADG1411 is powered off, while keeping input currents in the safe zone :

 

Example:

- input VS to sinus +/-10V signal through 1kohm, and VD=0

=> clamping occurs to VDD=0 or VSS=0 => input current +/-1mA, which is much less than 30mA maximum rating.

It seems that this cannot damage the component, am I right ?

 

In this case (no power) what is the behavior (ON or OFF) (ADG1411 is "normally open") ?

 

Thanks you,
