Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and 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 RESISTANCE

is specified for the worst-case conditions on a 4-layer board
in still air, in accordance with EIA/JESD51-1.

Airflow increases heat dissipation effectively, reducing θ
JA
. In
addition, more metal directly in contact with the package leads
from metal traces, through holes, ground, and power planes
reduces the θ
JA
. It is recommended that the exposed paddle be
soldered to the ground plane for the LFCSP package. There is
an increased reliability of the solder joints, and maximum
thermal capability of the package is achieved with the exposed
paddle soldered to the customer board.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
