Note 1:
All voltages are referenced to ground.
Note 2:
Limits at -40°C are guaranteed by design and are not production tested.
Note 3:
ICCS specified with VCC = 5.0V and SDA, SCL = 5.0V.
Note 4:
After this period, the first clock pulse is generated.
Note 5:
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the VIH(MIN) of the SCL
signal) to bridge the undefined region of the falling edge of SCL.
Note 6:
The maximum tHD:DAT only has to be met if the device does not stretch the LOW period (tLOW) of the SCL signal.
Note 7:
CB—total capacitance of one bus line in pF.
