2: A fast-mode I
Maximum pin capacitance = 10 pF for all I
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.+ # 107 = 1000 + 250 = 1250 ns (for 100 kHz-mode) before the SCL line is released.
This specification ensured by design. For the value required by the I
These parameters are for design guidance only and are not tested, nor characterized.
