Note 7-1

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 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.

*Stresses exceeding those listed in this section could cause permanent damage to the device. This is a stress rating

only. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Functional

operation of the device at any condition exceeding those indicated in Section 7.2, "Operating Conditions**", Section 7.5,

"DC Specifications", or any other applicable section of this specification is not implied.
