7. Limiting values
[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[2] The package thermal impedance is calculated from JESD51-7.
[3] For SO14 package; Ptot derates linearly with 8 mW/K above 70°C.
[4] For SSOP14, SSOP16 and TSSOP14 packages; Ptot derates linearly with 5.5 mW/K above 70°C.
