6. Functional description
[1] H = HIGH voltage state;
L = LOW voltage state;
X = don’t care;
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 packages: above 70 °C the value of P
tot
derates linearly at 8 mW/K.
For TSSOP14 packages: above 60 °C the value of P
tot
derates linearly at 5.5 mW/K.
For DHVQFN14 packages: above 60 °C the value of P
tot
derates linearly at 4.5 mW/K.
