NOTE: Most modern PCB designs use multi-layered boards. The data in the second row pertains to most designs.

For applications not requiring the use of the test clock, it can be

left floating. Though not required, but for additional protection, a

1k

Ω resister can be tied from the CLK input to ground.

All control pins have internal pull-ups and pull-downs;

additional resistance is not required but can be added for

additional protection. A 1k

Ω resister can be used.

All unused LVCMOS output can be left floating. We recommend

that there is no trace attached.
