Note
: 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.
