(1)
VCCI is the VCC associated with the data input port.
(2)
VCCO is the VCC associated with the output port.
(3)
All unused control inputs of the device must be held at VCCA or GND to ensure proper device operation and minimize power
consumption. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
(4)
For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL max = VCCI × 0.3 V.
(5)
For VCCA values not specified in the data sheet, VIH min = VCCA × 0.7 V, VIL max = VCCA × 0.3 V.
