*Pb-free PDIPs can be used for through hole wave solder processing

only. They are not intended for use in Reflow solder processing

applications.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the

device at these or any other conditions above those indicated in the operational sections of this specification is not implied.

NOTE:

JA is measured with the component mounted on an evaluation PC board in free air.
