Application Information
Recommendations for Unused Input and Output Pins
Inputs:
CLK Inputs
For applications not requiring the use of a clock input, it can be left
floating. Though not required, but for additional protection, a 1kΩ
resistor can be tied from the CLK input to ground.
LVCMOS Control Pins
All control pins have internal pullups or pulldowns; additional
resistance is not required but can be added for additional
protection. A 1kΩ resistor can be used.
