E) - Charged Device Model (AEC-Q100-011 Rev. B) - Machine Model (AEC-Q100-003 Rev. E) 4kV 1.25kV 250V Package Moisture Sensitivity Level MSL-1 Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only, and the functional operation of the device at these or any other conditions above those listed in the operational section of this specification is not implied. Exposure to absolute maximum ratings conditions for extended periods may affect device reliability. DC Operating Conditions (TA = -40 °C to + 85°C, VDD = 2.7V to 5.5V unless otherwise specified) Symbol Parameter Min Typ Max Units Notes VDD Power Supply Voltage 2.7 3.3 5.5 V IDD Power Supply Current @ SCK = 1.0 MHz @ SCK = 20.0 MHz - - 0.25 2.0 mA mA 1 ISB Standby Current 15 30 µA 2 ILI Input Leakage Current - ±1 µA 3 ILO Output Leakage Current - ±1 µA 3 VIH Input High Voltage 0.7 VDD VDD + 0.5 V VIL Input Low Voltage -0.3 0.3 VDD V VOH Output High Voltage @ IOH = -2 mA VDD – 0.8 - V VOL Output Low Voltage @ IOL = 2 mA - 0.4 V Notes 1.
