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.
Note 1: All supplies are fully tested at 25 V and an internal 20 V clamp exists for each supply.
Note 2: Logic operational for V
DT97-3 for more details).
Recommended Operating Conditions
