Note 1: 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 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 to use a clamp circuit.
*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 4.2, "Operating Conditions**", Section 4.4,
"DC Specifications", or any other applicable section of this specification is not implied.
