LVCMOS/LVTTL BUFFER DIVIDER
APPLICATION INFORMATION
RECOMMENDATIONS FOR UNUSED INPUT AND OUTPUT PINS
INPUTS:
CLK INPUT:
For applications not requiring the use of the test clock, it can be
left floating. Though not required, but for additional protection, a
1kΩ resister can be tied from the CLK input to ground.
OUTPUTS:
LVCMOS OUTPUT:
All unused LVCMOS output can be left floating. We recommend
that there is no trace attached.
CONTROL PINS:
All control pins have internal pull-ups and pull-downs;
additional resistance is not required but can be added for
additional protection. A 1kΩ resister can be used.
