(1) VCCI is the VCC associated with the input port. VCCO is the VCC associated with the output port.
(2) All unused inputs of the device must be held at VCC or GND for proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, SCBA004.
(3) Input transition rate of a single channel while the other channels are at a valid logic state and not switching.
