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

The exposed paddle must be soldered to the ground plane for the

LFCSP package. Soldering the exposed paddle to the customer

board increases the reliability of the solder joints, maximizing

the thermal capability of the package.

Per JEDEC 51-7, plus JEDEC 25-5 2S2P test board.

Per JEDEC JESD51-2 (still air) or JEDEC JESD51-6 (moving air).

Per MIL-Std 883, Method 1012.1.

Per JEDEC JESD51-8 (still air).

Typical θJA is specified for a 4-layer PCB with a solid ground

plane. 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.
