H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.
The minimum input voltage ratings may be exceeded if the input current ratings are observed.
The output voltage ratings may be exceeded if the output current ratings are observed.
For SO20 packages: above 70 C derate linearly with 8 mW/K.
For (T)SSOP20 packages: above 60 C derate linearly with 5.5 mW/K.
For DHVQFN20 and DHXQFN20U packages: above 60 C derate linearly with 4.5 mW/K.
