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 VSS; all currents are defined positive into any lead. The Thermal
Resistance and Power Dissipation ratings are measured under board mounted and still air conditions.

† VDD - VSS, VCC - COM, and VB - VS contain internal shunt zener diodes. Please note that the voltage
ratings of these can be limited by the clamping current.
†† For the rising and falling edges of step signal of 10V. VSS = 15V to 200V.
††† VSS ramps up from 0V to 200V.
