TS3USB3031: Back current into VCC

Part Number: TS3USB3031
Other Parts Discussed in Thread: TS3USBA225

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!

Austin Allen

    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
