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.

Note 1:
This IC contains a zener clamp structure between the chip VCC and COM which has a nominal breakdown
voltage of 15.6V (VCLAMP). Please note that this supply pin should not be driven by a DC, low impedance
power source greater than the diode clamp voltage (VCLAMP) as specified in the Electrical Characteristics
section.
