ELECTRICAL CHARACTERISTICS (continued)
(V
Note 2: All parameters are tested at T
Note 3: All digital inputs at V
Note 4: Guaranteed by design.
Note 5: C
Note 6: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V IL of the SCL signal) to bridge
Note 7: I
Note 8: Input filters on the SDA, SCL, and AD0 inputs suppress noise spikes less than 50ns.
