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. Additional information is shown in Figures 28 through 35.

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 ratings are tested with all supplies biased at 15V differential.Typical
