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 Fig. 1. For proper operation the device should be used

within the recommended conditions. The VS offset rating is tested with all supplies biased at 15 V

differential.
