Figure 1. I
Note 3: All parts will operate properly over the V
Note 4: Guaranteed by design and characterization.
Note 5: All timing specifications are guaranteed by design.
Note 6: A master device must provide a hold time of at least 300ns for the SDA signal to bridge the undefined region of SCL’s falling edge.
Note 7: C
Note 8: Input filters on SDA and SCL suppress noise spikes less than 50ns.
Note 9: Holding the SDA line low for a time greater than t
