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