Stresses above those listed above and below could cause permanent damage to the device. This is a
stress rating only and functional operation of the device at any other condition above those indicated in the
operation sections of this specification is not implied. 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. If
this possibility exists, it is suggested that a clamp circuit be used.
