Note 1: All parameters tested at TA = +25°C. Specifications over temperature are guaranteed by design.

Note 2: A master device must provide a hold time of at least 300ns for the SDA signal (referred to VIL of the SCL signal) to bridge

the undefined region of SCL’s falling edge.

Note 3: Guaranteed by design.

Note 4: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x VDD and 0.7 x VDD.

Note 5: ISINK ≤ 6mA. Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x VDD and 0.7 x VDD.

Note 6: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
