(1) V_CCI is the V_CC associated with the data input port.

(2) V_CCO is the V_CC 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 V_CCI 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 V_CCA or GND to ensure proper device operation and minimize power comsumption.

(5) For V_CCI values not specified in the data sheet, V_IH min = V_CCI × 0.7 V, V_IL max = V_CCI × 0.3 V.

(6) For V_CCA values not specified in the data sheet, V_IH min = V_CCA × 0.7 V, V_IL max = V_CCA × 0.3 V.

(7) Maximum input transition rate with < 4 channels switching simultaneously.
