CONDITIONS
VDD = 3.6 V, VIN = VSS, Ta = –40 ~ +70 °C
VDD = 3.0 V, VIN = VSS, Ta = –40 ~ +70 °C
VDD = 2.4 V, VIN = VSS, Ta = –40 ~ +70 °C
VDD = 5.5 V, VIN = VDD
VDD = 5.5 V, VIN = VSS
IOH = –1.0 mA
IOL = 2.0 mA
IOL = 1.0 mA (Nch Open Drain)
TPout = VDD (Nch Open Drain)
* If VIN pins are not VSS, Current Consumption increase in value.
