DATASHEET
Chapter 7 DC Parameters
7.1 Maximum Guaranteed Ratings
Note 7.1 Stresses above the specified parameters may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at any condition above
those indicated in the operation sections of this specification is not implied.
Note 7.2 When powering this device from laboratory or system power supplies, it is important that
the Absolute Maximum Ratings 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, it is suggested that a clamp circuit be used.
