2.1

Absolute Maximum Ratings

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.
