*Stresses above those listed above could cause permanent damage to the device. This is a stress rating only and func-
tional operation of the device at any other condition above those indicated in the operation sections of this specification
is not implied.
Note:
.
When powering this device from laboratory or system power supplies, it is important that the Absolute Max-
imum 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.
