H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
For SO20 packages: above 70 C derate linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 C derate linearly with 4.5 mW/K.
