Notes: 1. This parameter is ensured by characterization only.

2. AC measurement conditions:

Input rise and fall times:

≤ 50 ns

4. Device Operation

CLOCK and DATA TRANSITIONS: The SDA pin is normally pulled high with an external

device. Data on the SDA pin may change only during SCL low time periods (see Figure 4-4 on

page 7). Data changes during SCL high periods will indicate a start or stop condition as defined

below.
