Note: Stresses above those listed could cause 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.
