Functional description [1] H = HIGH voltage level; L = LOW voltage level; 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 SO16 packages: above 70 °C the value of P tot derates linearly at 8 mW/K. For TSSOP16 packages: above 60 °C the value of P tot derates linearly at 5.5 mW/K. Table 3. Function table[1] Control Input Output OE S nI0 nI1 nY HX X X Z LH X L L XH H LL X L HX H Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
