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 CHARACTERISTICS

Typical θJA is specified for both a 4-layer printed circuit board

(PCB) with a solid ground plane from the JEDEC 51-2 and an

8-layer PCB. The 8-layer PCB has 2 oz copper layers (M1 and

M8), 1 oz copper inner layers, and vias connecting to layers M2,

M5, and M7.

As shown in Table 7, airflow increases heat dissipation, which

reduces θJA. In addition, metal in direct contact with the

package leads from metal traces, through holes, ground, and

power planes, reduces the θJA.
