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

θJA is specified for the worst-case conditions, that is, a device

soldered in a circuit board for surface-mount packages.

Thermal performance is directly linked to printed circuit board

(PCB) design and operating environment. Careful attention to

PCB thermal design is required. The thermal resistance

numbers are defined per JESD51 standard.
