Stresses beyond those listed under absolute maximum ratings can cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods can affect device reliability.

(2)

100-kΩ series resistor is required if maximum slew rate is exceeded.
