Note 1: All parameters tested at TA=25 °C. Specifications over temperature are guaranteed by design.
Note 2: Guaranteed by design.
Note 3: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x VDD and 0.7 x VDD.
Note 4: ISINK ≤6mA. Cb =total capacitance of one bus line in pF. tR and tF measured between 0.3 x VDD and 0.7 VDD.
Note5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
