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 which has a nominal breakdown
voltage of 20V. This supply pin should not be driven by a DC, low impedance power source greater than the
VCLAMP specified in the Electrical Characteristics section.
Recommended Operating Conditions
For proper operation the device should be used within recommended conditions.
