Figure 21. Bus Timing Requirements Sequence
Table 12. AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 4.5 to 5.5V or 2.7 to 3.6V (except where noted).
2. Transmitter must internally provide a hold time to bridge the undefined region (300ns max) of the falling edge of SCL.
