PRELIMINARY

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

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