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

[2] For DIP16 packages: above 70 C the value of P_totderates linearly at 12 mW/K.

For SO16 packages: above 70 C the value of P_totderates linearly at 8 mW/K.

For SSOP16 and TSSOP16 packages: above 60 C the value of P_totderates linearly at 5.5 mW/K.
