(1)

VCCI is the VCC associated with the input port.

(2)

VCCO is the VCC associated with the output port.

(3)

All unused data inputs of the device must be held at VCCI or GND for proper device operation. Refer to the Implications of Slow or

Floating CMOS Inputs application report.

(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
