DS1856
Note 10: After this period, the first clock pulse is generated.
Note 11: The maximum tHD:DAT only has to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 12: A device must internally provide a hold time of at least 300ns for the SDA signal (see the VIH MIN of the SCL signal) to
bridge the undefined region of the falling edge of SCL.
Note 13: CB—total capacitance of one bus line, timing referenced to 0.9 x VCC and 0.1 x VCC.
Note 14: Guaranteed by design.
Typical Operating Characteristics
(VCC = 5.0V, TA = +25°C, for both 50k
