ADG3231 Vcc1 and Vcc2 on/off condition

I am trying to determine:


1. What the output  Y would be on Vcc2 side of the ADG3231 if Vcc1 is un-powered (disconnected) and the input A is tied to ground through 3MOhm resistor?


2. What the output would be if Vcc1 is powered and the input A is low through 3MOhms, and Vcc2 is disconnected.


The application is for serial communications with Tx and Rx lines going to a uP.  I am looking to know in the rtun-powered states if the outputs are determinant.
