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 terminals stated, all currents are defined positive into any lead. The thermal resistance and
power dissipation ratings are measured under board mounted and still air conditions.
Recommended Operating Conditions
Time for input of quasi resonant signals.
For the Quasi resonant signal inputted to the V
terminal at the time of quasi resonant operation, the
signal should be wider thant Tth(2)
