ELECTRICAL CHARACTERISTICS (continued)
(V
otherwise noted. Typical values are at T
Note 1: All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.
Note 2: P
Note 3: A 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 4: C
Note 5: Input filters on SDA, SCL, and ADD suppress noise spikes less than 50ns.
