TCA9617A: TCA9617A fast plus mode and fall time

Hi, for TCA9617A part with fast plus mode, I'm reading Tf at 0.5 nsec and 1.2nsec for SCL and SDA at the input of this part . I'm using this part as a level shifter bewtween source (1.8V) and EEPROM (3.3V). Is this fall time considered out of spec for this part? What about if the other parts in the bus also support  I2C fast mode plus? I'm referring to page 47 of the UM10204 document in footnote 8, which says that min Tf applies for backward compatible mode. Please advise.
