Hi,
Is there leak path from INA/B pins into VCC?
In other words, does VCC rise up when VCC is floating and INA/B are high?

No; LVC inputs are overvoltage tolerant. See [FAQ] Can the input voltage (Vi) to my logic device be higher than the supply voltage (Vcc)?
Clemens-san,
Thank you for your comment.
However it looks that this is no answer for my question.
Where is mentioned it on this article?

The linked article describes how the current through the positive clamp diode is a problem. It does imply (but not explicitly say) that devices without a positive clamp diode have no such current and therefore are overvoltage tolerant.
I'm understanding what you say.
I would like to know if VCC rise up when VCC is floating and INA/B are high.
Is it "no"?
There is no leakage between the inputs and VCC; it is safe to apply voltages to the inputs at any time.
Clemens-san,
Thank you for your comment, I refer it.
I wait also TIer's comment.
