Note 1: 100% production tested at TA = +25°C and TA = +85°C. Specifications at TA = -40°C are guaranteed by design.
Note 2: Device may be supplied from any one of IN1–IN4 or VCC.
Note 3: The internal supply voltage, measured at VCC, equals the maximum of IN1–IN4.
Note 4: Versions Q and R require that power be applied through VCC.
ELECTRICAL CHARACTERISTICS (continued)
(VIN1–VIN4 or VCC = 2.7V to 5.8V, WDI = GND, MARGIN = MR = BP, TA = -40°C to +85°C, unless otherwise noted. Typical values are
at TA = +25°C.) (Notes 1, 2)
