Functional description [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care. 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. 8. Recommended operating conditions Table 3. Function table[1] Input Output nA nB nY LLL XH H HX H Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
