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 lead. The

thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.

† This IC contains a voltage clamp structure between the chip VCC and COM which has a nominal breakdown

voltage of 15.6 V. Please note that this supply pin should not be driven by a DC, low impedance power

source greater than the VCLAMP specified in the Electrical Characteristics section.
