Maximum pin capacitance = 10 pF for all I
A Fast mode I
parameter 107 ≥ 250 ns must then be met. This will automatically be the case if the device does not stretch
the LOW period of the SCL signal. If such a device does stretch the LOW period of the SCL signal, it must
output the next data bit to the SDA line, parameter 102 + parameter 107 = 1000 + 250 = 1250 ns (for
100 kHz mode), before the SCL line is released.
