= capacitance of one bus line in pF.
Note that the maximum t
F
for the SDA and SCL bus lines quoted at 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
.
