Note 1:
All parameters are tested at T
A
= +85°C. Specifications over temperature are guaranteed by design.
Note 2:
Timing specifications are guaranteed by design.
Note 3:
The serial interface resets when SCL is low for more than t

.
Note 4:
A transition must internally provide at least a hold time to bridge the undefined region (300ns max) of SCL’s falling edge.
