For operation between published voltage ranges, refer to worst-case parameter in both ranges.
The SDA and SCL propagation delays are dominated by rise times or fall times. The fall times are mostly internally controlled and are
only sensitive to load capacitance. The rise times are RC time constant controlled and therefor a specific numerical value can only be
given for fixed RC time constants.
The SDA HIGH to LOW propagation delay includes the fall time from V
SCL fall time from the quiescent HIGH (usually V
included which make the fall time almost independent of load capacitance.
The SDA or SCL LOW to HIGH propagation delay includes the rise time constant from the quiescent LOW to 0.5V
or EXPSCL2, the rise time constant for the quiescent LOW to 0.5V
the quiescent external driven LOW to 0.7V
external resistance and total capacitance for the various nodes.
