ADG1434 Powered Down Properties

Background of Application:

We have 4 independent analog signal lines that range from -12V to 12V coming from an external device.


Configuration of ADG1434:

Source Terminals A : Input analog signals from external device

Source Terminals B : Ground

Drain Terminals : Output



1)  Given the above conditions what natural state would the ADG1434 be in if VDD & VSS are not powered?



2)  Would applying an input analog signal to Source Terminal A cause damage to an unpowered ADG1434?
