Characterized but not tested.
This specification ensured by design.
These parameters are for design guidance only and are not tested, nor characterized.
Maximum pin capacitance = 10 pF for all I
A fast-mode (400 KHz) I
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 + # 107 = 1000 + 250 = 1250 ns (for 100 kHz-mode) before the SCL line is released.
