11 OPERATIONAL DESCRIPTION

11.1 Maximum Guaranteed Ratings

Operating Temperature Range ................................................................................................................... 0

oC to +70oC

Storage Temperature Range ................................................................................................................... -55

o to +150oC

Lead Temperature Range ......................................................................................... Refer to JEDEC Spec. J-STD-020

Note

: Stresses above those listed above and below could cause permanent 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.
