 Thanks!

Hi AWANG01, 
 Apologies for the late reply. Do you mean of Power Off is no Vdd and Vss supply? If yes, I suggest that if you will have an Analog input during power off, you may consider ADG508F instead. Using normal switches in that setup might cause problems like latch-up due to overvoltage status. 
 Might also be good to check this article about fault protected switch/mux: Switch and Multiplexer Design Considerations for Hostile Environments | Analog Devices
