Functional description

[1]

H = HIGH voltage level; L = LOW voltage level; Z = high-impedance OFF-state.

7.

Limiting values

[1]

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

[2]

For SO14 package: Ptot derates linearly with 8 mW/K above 70 C.

For (T)SSOP14 packages: Ptot derates linearly with 5.5 mW/K above 60 C.
