INPUTS:

CLK INPUT:

For applications not requiring the use of a clock input, it can

be left floating. Though not required, but for additional

protection, a 1k

Ω resistor can be tied from the CLK input to

ground.

LVCMOS CONTROL PINS:

All control pins have internal pull-ups or pull-downs; additional

resistance is not required but can be added for additional

protection. A 1k

Ω resistor can be used.

RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS

OUTPUTS:

LVCMOS OUTPUT:

All unused LVCMOS output can be left floating. We

recommend that there is no trace attached.
