Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM, all currents are defined positive into any pin. The thermal
resistance and power dissipation ratings are measured under board mounted and still air conditions.
