Specification, 17.02.00
2)C
b= capacitance of one bus line in pF.
Note that the maximum tF for the SDA and SCL bus lines quoted at 300ns is
longer than the specified maximum tOF for the output stages (250ns).This
allows series protection resistors to be connected between the SDA / SCL pins
and the SDA /SCL bus lines without exceeding the maximum specified tF.
