Note 10: A master device must provide a data hold time for SDA (referred to VIL of SCL) in order to bridge the undefined region of
SCL’s falling edge (see Figure 1).
Note 11: The minimum value is specified at +25°C.
Note 12: CB = total capacitance of one bus line in pF.
Note 13: fSCL must meet the minimum clock low time plus the rise/fall times.
