CB3T and I2C

Hi.

I design 2.5V <-> 3.3V interface by SN74CB3T16210 and signal include I2C.

Some of 3.3V side may change 2.5V and another is fix to 3.3V.

So, I connect pull-up 2.2k throught 3.3V source at the 3.3V side and VCC connect 2.5V

By the SCDA008, figure 35 is very similar to I2C, so I think CB3T can use I2C level translate.

However, next section that '6. Conclusion' I2C mention in CBT-C and CB3Q, CB3T is not.

Can CB3T translate level in I2C interface?

If can, 2.5V side need pull-up?

If can not, recommend please another solution.

Thanks.
