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. 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).
