TS3USBCA4: powered off support

Part Number: TS3USBCA4
Other Parts Discussed in Thread: TS3USB3031

Dear TI experts,

I'm considering the TS3USBCA410 as a replacement of the currently unavailable TS3USB3031 in a non-demanding application (UART up to 1Mbps).

Unlike other devices, there is no specification of the SBU current when the device is not powered (VCC = 0). On the other hand, the absolute maximum voltage is not related to VCC.

Is it allowed to apply a voltage up to 3.3V to the SBU pins, when VCC = 0V? Will there be any back powering into VCC?
