(1) VCCI is the VCC associated with the data input port.
(2) VCCO is the VCC associated with the output port.
(3) All unused or driven (floating) data inputs (I/Os) of the device must be held at logic HIGH or LOW (preferably VCCI or GND) to ensure proper device operation and minimize power. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
(4) All unused control inputs must be held at VCCA or GND to ensure proper device operation and minimize power comsumption.
(5) For VCCI values not specified in the data sheet, VIH min = VCCI  × 0.7 V, VIL max = VCCI  × 0.3 V.
(6) For VCCA values not specified in the data sheet, VIH min = VCCA  × 0.7 V, VIL max = VCCA  × 0.3 V.
(7) Maximum input transition rate with < 4 channels switching simultaneously.
