TXB0302: Question about data rate (timing requirements).

Hi,

Our design team have a question about P/N TXB0302DQMR. See question below:

Q1: Is this the maximum possible data rate? or is it guaranteed to do that amount?

See information from the datasheet:

Timing Requirements

Data rate:  CL= 15pF    VCCA: 1.8 to 3.6 V VCCB; 1.8 to 3.6 V  Max 140 Mbps.

Thanks,
