SN74AUP1G17: Ioff Feature

Part Number: SN74AUP1G17

Tool/software:

I would like to verify that the inputs of the SN74AUP1G17 are indeed high impedance when VCC is unpowered. I plan to have two of these in parallel wired to the same input signal. However, one of them will sometimes be powered off. I want to make sure that the input of the one powered off will be high impedance and not affect the other one. As I understand it, the Ioff feature will allow me to do this. I also understand that even though the input will be high impedance, there could also be up to 0.2uA of leakage current.
