Figure 9. Bus Timing Requirements Sequence
Note: P = STOP and S = START
Table 2. AC Characteristics
Note: 1. Valid for Ambient Operating Temperature: TA = –40 to 85°C; VCC = 2.0 to 5.5V (except where noted).
2. Transmitter must internally provide a hold time to bridge the undefined region (300ns max.) of the falling edge of SCL.
