AC Characteristics
Applicable over recommended operating range from:
T
in Note 2.
Notes:1. This parameter is characterized and not 100% tested.
Device Operation
Clock and Data Transitions:
during SCL low time periods (refer to Figure 4). Data changes during SCL high periods will indicate a
start or stop condition as defined below.
Endurance
A
The SDA pin is normally pulled high with an external device. Data on the SDA pin may change only
= -40℃ to +85℃, V
