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.
Note 1: Logic operational for VS of -5 V to +600 V. Logic state held for VS of -5 V to -VBS. (Please refer to the Design Tip
DT97-3 for more details).

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.
