Absolute Maximum Ratings

Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-

eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured

under board mounted and still air conditions.

Recommended Operating Conditions

The Input/Output logic timing diagram is shown in figure 1. For proper operation the device should be used within the

DT97-3 for more details).

Note 2: HIN and LIN pins are internally clamped with a 5.2V zener diode.
