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 pin. 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 20.8V. This supply pin should not be driven by a DC, low
impedance power source greater than the VCLAMP specified in the Electrical
Characteristics section.
This IC contains a voltage clamp structure between the CMP and COM which has a
†† nominal breakdown voltage of 10.2V. This pin should not be driven by a DC, low
impedance power source greater than the VZCMP specified in the Electrical
Characteristics section.
