NOTES:

4. VCCI is the VCC associated with the data input port.

5. VCCO is the VCC associated with the output port.

6. All unused data inputs of the device must be held at VCCI or GND to ensure proper device operation. Refer to the TI application report,

Implications of Slow or Floating CMOS Inputs, literature number SCBA004.
