TCA9555: Address Pin Floating

Part Number: TCA9555

Hi expert,

Customer has a production product  used TCA9555 and TCA9548 and forgot to mount pull high/low resistor on the board of address pins.

So far didn't see any issues but wondering what would be the status of address pin if floating? We want to know the impact of the risk. 

Would it be high/low/unknown?

Thanks,

Allan
