[1] If at least one of VCC(A) or VCC(B) is at GND level, the device goes into suspend mode.

[2] nAn, nDIR and nOE are referenced to VCC(A); nBn is referenced to VCC(B).

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 6.5 V.

[4] For SOT403-1 (TSSOP16) package: Ptot derates linearly with 8.5 mW/K above 91 °C.

For SOT763-1 (DHVQFN16) package: Ptot derates linearly with 11.2 mW/K above 106 °C.
