Note 1: Operating Characteristics are over Standard Operating Conditions unless otherwise specified.
Note 2: Equivalent to discharging a 100pF capacitor via a 1.5kΩresistor (Human body model).
Note 3: Excluding any load current and VPU/VSW source current to 1.5kΩ and 15kΩ pull-up and pull-down resistors (200 µA).
Note 4: Current is drawn from VBUS of Host when device is a peripheral.
Note 5: Low current ideal for battery powered applications.
