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 zener clamp structure between the chip VCC and COM, with a nominal breakdown
voltage of 15.6 V. Please note that this supply pin should not be driven by a low impedance DC power source
greater than VCLAMP specified in the electrical characteristics section.
