[1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state.

[2] The input circuit of the data I/O is always active.

[3] When either VCC(A) or VCC(B) is at GND level, the device goes into suspend mode.

Table 5. 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 SC-88 package: above 87.5 °C the value of Ptot derates linearly with 4.0 mW/K.

For XSON6 package: above 118 °C the value of Ptot derates linearly with 7.8 mW/K.
