Functional description [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state. [2] The nAn, nDIR and nOE input circuit is referenced to VCC(A); The nBn input circuit is referenced to VCC(B). [3] If at least one of VCC(A) or VCC(B) is at GND level, the device goes into suspend mode. 7. Limiting values [1] The minimum input voltage ratings and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] VCCO is the supply voltage associated with the output port. [3] VCCO + 0.5 V should not exceed 4.6 V. [4] For SO16 package: above 70 °C derates linearly with 8 mW/K. For TSSOP16 package: above 60 °C the value of P tot derates linearly at 5.5 mW/K. For DHVQFN16 package: above 60 °C the value of P tot derates linearly at 4.5 mW/K. Table 3.
