Note 1: Characterized but not 100% tested.

2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region

(minimum 300 ns) of the falling edge of SCL to avoid unintended generation of Start or Stop conditions.

3: CB = total capacitance of one bus line in pF.

4: This parameter is not tested but ensured by characterization.
