Note 1: All parameters tested at TA = +25掳C. Specifications over temperature are guaranteed by design.
Note 2: Guaranteed by design.
Note 3: 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鈥檚 falling edge.
Note 4: Cb = total capacitance of one bus line in pF. tR and tF measured between 0.3 x V+ and 0.7 x V+, ISINK
鈮� 6mA.
Note 5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
