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.

All supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply.
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 S and V SS offset rating are tested with all supplies biased at a 15 V
differential.
