[1] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only
and functional operation of the device at these or any other conditions beyond those indicated under
“recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal
environment can create junction temperatures which are detrimental to reliability. The maximum junction
temperature of this integrated circuit should not exceed 150 C.
[3] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
