Mode (Note 2)

Note 1: As transmitter the device must provide this 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.

2: 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.
