SERIAL INTERFACE TIMING CHARACTERISTICS (Figure 3) (continued)
(IN1 = GND, V IN2 –V IN7 = 2.7V to 5.5V, V IN8 = 10V, GPI_ = GND, MARGIN = MR = DBP, T A = -40°C to +85°C, unless otherwise
noted. Typical values are at T A = +25°C.) (Notes 1, 2, 3)

Note 1: 100% production tested at T A = +25°C and T A = +85°C. Specifications at T A = -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 <
V IN1 < 6.5V and at least one of V IN2 –V IN5 is between 2.7V and 5.5V, while the remaining V IN2 –V IN5 are between 0 and 5.5V.
Specifications are also guaranteed if V CC is externally supplied.
Note 3: Device may be supplied from any one of IN1 to IN5, or V CC (see the Powering the MAX6889/MAX6890/MAX6891 section).
Note 4: The internal supply voltage, measured at V CC , equals the maximum of IN2 to IN5 if V IN1 = 0V, or equals 5.4V if V IN1 > 6.5V.
For 4V < V IN1 < 6.5V and V IN2 –V IN5 > 2.7V, the input that powers the device cannot be determined.
Note 5: C BUS = total capacitance of one bus line in pF. Rise and fall times are measured between 0.1 x V BUS and 0.9 x V BUS .
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
(V IN1 = 6.5V to 13.2V, V IN8 = 10V, V IN_ = 2.7V to 5.5V, GPI_ = GND, MARGIN = MR = DBP, T A = +25°C, unless otherwise noted.)
