PORT AND TIMING CHARACTERISTICS
(V+ = +1.71V to +5.5V, T
TIMING CHARACTERISTICS
(V+ = +1.71V to +5.5V, T
Note 1: All parameters tested at T
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 V
Note 4: C
Note 5: Input filters on the SDA and SCL inputs suppress noise spikes less than 50ns.
