SN74LVCC3245A: operation at VccA=3.3V > 0V(power down), VccB=5V

Part Number: SN74LVCC3245A

Hi expert,

Customer is using SN74LVCC3245A for 3.3V to 5V level transition.

In normal case, VccA=3.3V, VccB=5V.

However, VccA will go down to 0V at power down. (VccB will keep 5V)

Is it no problem?

Also, in this case, could you please let me know the state of A port and B port? (Low, High or High-Z, something like that)

Thanks

Muk
