Note 9.1 Stresses above the specified parameters may cause permanent damage to the device. This is a stress rating only. Functional operation of the device at any condition above those indicated in the operation sections of this specification is not implied.

Note 9.2 When powering this device from laboratory or system power supplies the Absolute Maximum Ratings must not be exceeded or device failure can result. Some power supplies exhibit voltage spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on the AC power line may appear on the DC output. When this possibility exists, a clamp circuit should be used.
