Note 1: Not 100% tested. C
2: As a transmitter, the device must provide an internal minimum delay time to bridge the undefined region (min-
imum 300 ns) of the falling edge of SCL to avoid unintended generation of START or STOP conditions.
3: The combined T
suppression. This eliminates the need for a T
4: This parameter is not tested but guaranteed by characterization. For endurance estimates in a specific appli-
cation, please consult the Total Endurance Model which can be obtained on our BBS or website.
