Note 1: Specifications guaranteed for the stated global conditions. The device also meets the parameters specified when 0 < VIN1
< +6.5V, and at least one of VIN3–VIN6 is between +2.7V and +5.5V, while the remaining VIN3–VIN6 are between 0 and
+5.5V.
Note 2: Device may be supplied from any one of IN_, except IN2 and IN6.
Note 3: The internal supply voltage, measured at ABP, equals the maximum of IN3–IN5 if VIN1 = 0, or equals +5.4V if VIN1 > +6.5V.
For +4V < VIN1 < +6.5V and VIN3–VIN5 > +2.7V, the input that powers the device cannot be determined.
Note 4: CBUS = total capacitance of one bus line in pF. Rise and fall times are measured between 0.1 x VBUS and 0.9 x VBUS.
Note 5: Input filters on SDA, SCL, A0, and A1 suppress noise spikes < 50ns.
Note 6: An additional cycle is required when writing to configuration memory for the first time.
TIMING CHARACTERISTICS
(IN1 = GND, VIN2–VIN6 = +2.7V to +5.5V, GPI_ = GND, MARGIN = MR = DBP, TA = -40°C to +85°C, unless otherwise noted. Typical
values are at TA = +25°C.) (Notes 1, 2)
