TS3USB221: Channel transition

Shinya Sawamoto

Part Number: TS3USB221

Hello team,

I'd like to know how the TS3USB221 behave during channel transition.
I wonder if the VIN see HIZ impedance in tON period in the figure below to know there is possible to happen a short voltage spike event during the transition.

Thanks in advance.

from lab data, we didn't see spike when Ton.

Thanks for the feedback.
Is that mean that a HIZ period during transition is very short time and not need to concern for users?
