[1] 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.
[2] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
