Capacitive load for each bus line
1 See Figure 2.
2 Guaranteed by design and characterization; not production tested.
3 A master device must 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 SCL’s
falling edge.
4 CB is the total capacitance of one bus line in pF. tR and tF measured between 0.3 VDD and 0.7 VDD.
