<p>As mentioned tri-state is typically used for buses. You don't
want to use pull-downs on those. You use pull-ups to keep the bus
from floating. If you use pull-downs you're fighting the resistors
when the signals go high. If you use a high resistance with
pull-downs with CMOS it will probably work. If you use a lower
resistance then you may not be able to pull the signal high when
needed.</p>
