NOTES: 4. V
CCI
is the V
CC
associated with the data input port.
5. V
CCO
is the V
CC
associated with the output port.
6. All unused data inputs of the device must be held at V
CCI
or GND to ensure proper device operation. Refer to the TI application report,
Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
