CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress ratings only and operation of the

device at these or any other conditions above those indicated in the operational sections of the specifications is not implied.

NOTES:

3. When the voltage across ACSET and DCSET is below 0V, the current through ACSET and DCSET should be limited less than 1mA.
