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