Table 5: I2C Bus DC Characteristics

Table 6: I2C Bus AC Characteristics

Note 1: A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIH(MIN) of the SCL signal) to bridge the undefined region of the falling edge

of SCL.

Note 2: I2C inputs are 5V tolerant.
