Highest input voltage to analog switch ADG714 when gate is off

Hello everyone,

 

What's the highest input voltage an analog gate such as ADG714 can withstand without harming the device when it is switched off? This is, when the gate is switched on the input signal can only swing from Vss to Vdd, that's clearly specified in the datasheet. However, I would like to apply higher voltages than Vdd and lower voltages than Vss when the gate is closed.

 

In my application Vss=0, Vdd=3.3V and I would like to apply voltages as high as +15V and as low as -15V. Is this possible?

 

Thank you for your advice

Victor
