Note 1: Specifications are 100% tested at T A = +25 N C. Limits over the operating range are guaranteed by design and
characterization.
Note 2: All voltages are referenced to GND.
Note 3: Test is performed on unmounted/unsoldered parts.
Note 4: The voltage is trimmed and verified with 16x averaging.
Note 5: This current is always present.
Note 6: The IC enters shutdown mode after SCL < V IL and SDA < V IL for longer than 2.5s.
Note 7: Timing must be fast enough to prevent the IC from entering sleep mode due to bus low for period > t SLEEP .
Note 8: f SCL must meet the minimum clock low time plus the rise/fall times.
Note 9: The maximum t HD:DAT has to be met only if the device does not stretch the low period (t LOW ) of the SCL signal.
Note 10: This device internally provides a hold time of at least 100ns for the SDA signal (referred to the V IH,MIN of the SCL signal)
to bridge the undefined region of the falling edge of SCL.
Note 11: Filters on SDA and SCL suppress noise spikes at the input buffers and delay the sampling instance.
Note 12: C B is total capacitance of one bus line in pF.
