ABSOLUTE MAXIMUM RATINGS
Table 5.
Parameter
ELECTRICAL
ENVIRONMENTAL
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.
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 proprie-
tary 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.

the thermal resistance through heat-sink path.
Airflow increases heat dissipation effectively reducing θ
more metal directly in contact with the package leads, from
metal traces, through holes, ground, and power planes, reduces
