TCA9617B: TCA9617B - level shifting between 3.3V and 1.8V @ 800K speed

Part Number:TCA9617B

Hi,

I'm using the TCA9617B as a level shifter between Aardvark (3.3V level) to a Slave device (1.8V level).Since side B can't support 1.8V level I connected the Slave device to Side A and the Master device to Side B.Is it a valid connection? What would be the recommanded typical pull-up resistors for using 800K speed?

Regards,

Matty
