The temperature ranges quoted apply to all package types.
Many package types are available and extended temperature
ranges can be offered for some. Further information is available
on request.
Stresses above those listed in the Absolute Maximum
Ratings may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at
these conditions, or at any other condition above those indicated
in the operations section of this specification, is not implied.
Exposure to Absolute Maximum Rating conditions for extended
periods may affect device reliability.
