1. Stresses above those listed in Absolute Maximum Ratings may cause damage to the device. Functional operation at conditions other

than the operating conditions specified is not implied. Only one Absolute Maximum Rating should be applied at any one time.

2. Human body model is 100pF capacitor discharged through a 1.5kΩ resistor into each pin.

3. Mounted on a demo board (FR4, in still air). Exposed pad must be mounted to PCB.

4. Derate 20mW/°C above 25°C.
