(1) VCCI is the VCC associated with the data input port.
(2) VCCO is the VCC associated with the output port.
(3) All unused control inputs of the device must be held at VCCA or GND to ensure proper device operation and minimize power consumption. 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 VCCA values not specified in the data sheet, VIH min = VCCA × 0.7 V, VIL (max) = VCCA × 0.3 V.
