Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the

operational section of this specification is not implied.

Operation beyond the maximum operating conditions for

extended periods may affect product reliability.

THERMAL RESISTANCE

Thermal performance is directly linked to printed circuit

board (PCB) design and operating environment. Careful

attention to PCB thermal design is required.

θJA is the natural convection junction to ambient thermal

resistance measured in a one cubic foot sealed enclosure. θJC is

the junction to case thermal resistance.
