(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. All unused control inputs of the
device must be held at V_CCA or GND to ensure proper device operation. See the TI application report, Implications of Slow or Floating
CMOS Inputs, literature number SCBA004.
(4) For data input values not specified in the data sheet, V_IH min = V_CCI × 0.7 V, V_IL max = V_CCI × 0.3 V.
(5) For control input values not specified in the data sheet, V_IH min = V_CCA × 0.7 V, V_IL max = V_CCA × 0.3 V.
