(1) VCCI is the VCC associated with the input port.
(2) VCCO is the VCC associated with the output port.
(3) All unused data inputs of the device must be held at VCCI or GND to assure proper device operation. See Implications of Slow or Floating CMOS Inputs (SCBA004).
(4) For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL max = VCCI × 0.3 V.
(5) For VCCI values not specified in the data sheet, VIH min = VCCA × 0.7 V, VIL max = VCCA × 0.3 V.
