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 spec-

ification 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 tran-

sients on the AC power line may appear on the DC output. If this possibility exists, it is suggested that a

clamp circuit be used.
