[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
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).

[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 Ptot derates linearly at 5.5 mW/K.
For DHVQFN16 package: above 60 °C the value of Ptot derates linearly at 4.5 mW/K.
