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