TS3USB3000: limitation between VCC and I/O level

Part Number: TS3USB3000

Hi, 

My customer is having below question:

  1. As the datasheet describe all I/O pins to be in high-impedance mode when power is OFF, but how about the I/O pins state when VCC level is 0V~2.7V
  2. If any limitation between VCC and I/O level, for example, the I/O level(3.3V) is higher VCC level(2.8V).

  • 1: Vcc is 0-2.7v, IO pin may have higher impedance than those on -resistance on datasheet.

    2:   it should work as normal when IO is 3.3v but Vcc is 2.8V
