Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device 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 and maximizes

the thermal capability of the package.

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

plane. As shown, airflow improves 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.
