= capacitance of one bus line in pF
Note that the maximum t
F
for the SDA and SCL bus lines quoted in table above (300ns) is longer than the specified maximum t
OF
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 t
F
.
