Input Capacitance

Note 7: After this period, the first clock pulse is generated.

Note 8: The maximum t_HD:DAThas only to be met if the device does not stretch the LOW period (t_LOW) of the SCL signal.

Note 9: A fast-mode device can be used in a standard mode system, but the requirement t

>250ns must then be met. This is automatically

SU:DAT

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 t_RMAX+ t_SU:DAT(1000 + 250 = 1250ns) before the SCL line is released.

Note 10: C_B: Total capacitance of one bus line in pF.
