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 through VIN6 is between +2.7V and +5.5V, while the remaining VIN3 through VIN6 are
between 0 and +5.5V.
Note 2: Device may be supplied from any one of IN_, except IN2.
Note 3: The internal supply voltage, measured at ABP, equals the maximum of IN3–IN6 if VIN1 = 0, or equals +5.4V if VIN1 >
+6.5V. For +4V < VIN1 < +6.5V and VIN3 through VIN6 > +2.7V, the input that powers the device cannot be determined.
Note 4: 100% production tested at TA = +25°C and TA = +85°C. Specifications at TA = -40°C are guaranteed by design.
Note 5: 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 6: Input filters on SDA, SCL, A0, and A1 suppress noise spikes < 50ns.
Note 7: An additional cycle is required when writing to configuration memory for the first time.
TIMING CHARACTERISTICS
(IN1 = GND, VIN2 = +10V, VIN3–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)
