Dear Specialists,
My customer is considering SN74LVCC3245A and have a question.
I would be grateful if you could advise.

We are considering whether we can supply only 3.3V to update the F/W of 3.3V microcontrollers.
Because it is not necessary to operate the SN74LVCC3245A when writing to F/W.
When VCCA: 3.3V, VCCB: 0V, is there a possibility of damage?
A1-8, DIR may be applied with 3.3V.
G # is fixed 3.3V (inactive).
Is it possible to use under these conditions?

I appreciate your great help in advance.
Best regards,
Shinichi
