Chapter 6 DC Parameters

6.1

Maximum Guaranteed Ratings

Notes:



Stresses above the specified parameters could cause permanent damage to the device. This is a

stress rating only. Therefore, functional operation of the device at any condition above those

indicated in the operation sections of this specification are 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. When this possibility exists, it is

suggested that a clamp circuit be used.
