_______________________________________________________________________________________
Note 1: 100% production tested at TA = +25°C and TA = +85°C. Specifications at TA = -40°C are guaranteed by design.
Note 2: Specifications are guaranteed for the stated global conditions. The device also meets the parameters specified when 0 <
VIN1 < 6.5V and at least one of VIN2–VIN5 is between 2.7V and 5.5V, while the remaining VIN2–VIN5 are between 0 and 5.5V.
Specifications are also guaranteed if VCC is externally supplied.
Note 3: Device may be supplied from any one of IN1 to IN5, or VCC (see the Powering the MAX6889/MAX6890/MAX6891 section).
Note 4: The internal supply voltage, measured at VCC, equals the maximum of IN2 to IN5 if VIN1 = 0V, or equals 5.4V if VIN1 > 6.5V.
For 4V < VIN1 < 6.5V and VIN2–VIN5 > 2.7V, the input that powers the device cannot be determined.
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.
Typical Operating Characteristics
(VIN1 = 6.5V to 13.2V, VIN8 = 10V, VIN_ = 2.7V to 5.5V, GPI_ = GND, MARGIN = MR = DBP, TA = +25°C, unless otherwise noted.)
