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
recommended conditions. The V and V offset rating are tested with all supplies biased at 15V differential.
