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 RESISTANCE

is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages and
measured using a standard 4-layer board, unless otherwise
specified.
