Figure 8. Bus Timing Requirements Sequence

Table 2. 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.
