TIMING CHARACTERISTICS
(V
(V
Note 8: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V
Note 9: Cb = total capacitance of one bus line in pF. t
Note 10: An input filter on the SDA and SCL input suppresses noise spikes less than 50ns.
Note 11: Guaranteed by design.
