(1) V_CCI is the V_CC associated with the input port.
(2) V_CCO is the V_CC associated with the output port.
(3) 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.
