TS3USB221A: TS3USB221A use case for 5V Vi & Vo

Part Number: TS3USB221A

Hi,

I would like to get a clarification on the I/O of the TS3USB221A if it's compatible with 5V level input/output voltage.

With reference to the datasheet, we got to know that the V I/O accepts signals up to 5.5V. Does this means the Pin 1, 2, 3, 4, 7 and Pin 8 is capable of supporting signals that drive up to 5.5V (max)?

The reason behind this question is that we plan to use the second channel of the switch to support 5V signals, which means at least Pin 3, 4, 7 and Pin 8 needs to support 5V signals while the VCC stays as 3.3V. Are there any additional considerations needs to be taken in this case?

Although the under section 6.3 Recommended Operating Conditions says it supports, but I would like to confirm that V I/O pins covers Pin 1, 2, 3, 4, 7 and Pin 8 as well in this case. Thanks.

Regards,

Leo
