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