Hi team,

For either TS3USB3031 or TS3USBA225, when VCC is low, is there any back current concern between Diff pair I/O and VCC? Also between Select I/O and VCC?

Thank you!

Hello Austin:

The Diff pair IO pins and control IO pins of TS3USB3031 and TS3USBA225 are not fail safe pins, we do have concern for back drive current between Diff pair I/O and VCC as well as Select I/O and VCC .

Regards
