All voltages are referenced to ground.
Limits at -40°C are guaranteed by design and are not production tested.
I
CCS
specified with V
CC
= 5.0V and SDA, SCL = 5.0V.
After this period, the first clock pulse is generated.
A device must internally provide a hold time of at least 300ns for the SDA signal (referred to the V
IH(MIN)
of the SCL
signal) to bridge the undefined region of the falling edge of SCL.
The maximum t
HD:DAT
only has to be met if the device does not stretch the LOW period (t
LOW
) of the SCL signal.
C

—total capacitance of one bus line in pF.
