7. Functional description
[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 V
CC(A)
or V
CC(B)
is at GND level, the device goes into suspend mode.
8. 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] V
CCO
is the supply voltage associated with the output port.
[3] V
CCO
+ 0.5 V should not exceed 6.5 V.
[4] For SC-88 package: above 87.5 C the value of P
tot
derates linearly with 4.0 mW/K.
For XSON6 package: above 118 C the value of P
tot
derates linearly with 7.8 mW/K.
