pF
Note 1: All parameters are tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: All digital inputs at V+ or GND.
Note 3: Guaranteed by design.
Note 4: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.8V and 2.1V.
Note 5: 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 6: ISINK
≤ 6mA. Cb = total capacitance of one bus line in pF. tR and tF measured between 0.8V and 2.1V.
Note 7: Input filters on the SDA, SCL, and AD0 inputs suppress noise spikes less than 50ns.
