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.
It is not recommended to operate the device at temperatures above +125°C
for greater than a total of 5% of the lifetime of the device. Any exposure
beyond this limit will affect device reliability.
Values relate to the package being used on a 2-layer PCB. See

Junction-to-Case resistance is applicable to components featuring a
preferential flow direction, e.g. components mounted on a heat sink.
Junction-to-Ambient resistance is more useful for air-cooled PCB mounted
components.

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.
