Note 3: All currents into the device are negative; currents out of the device are positive. All voltages are referenced to device
Note 4: Parameters are 100% production tested at +25°C, limits over temperature are guaranteed by design.
Note 5: The V
Note 6: Guaranteed by design, not production tested.
Note 7: 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
Note 8: C
Note 9: Input filters on SDA, SCL, and ADD suppress noise spikes less than 50ns.
