I
(V+ = 2.4V to 3.6V, T
Note 1: All parameters are tested at T
Note 2: All digital inputs at V+ or GND.
Note 3: Guaranteed by design.
Note 4: C
Note 5: A master device must provide a hold time of at least 300ns for the SDA signal (referred to V
Note 6: I
Note 7: Input filters on the SDA, SCL, and AD0 inputs suppress noise spikes less than 50ns.
