3-State Long Line Drivers
A pair of 3-state buffers is associated with each CLB in the
array. These 3-state buffers (BUFT) can be used to drive
signals onto the nearest horizontal longlines above and
below the CLB. They can therefore be used to implement
multiplexed or bidirectional buses on the horizontal long-
lines, saving logic resources.
There is a weak keeper at each end of these two horizontal
longlines. This circuit prevents undefined floating levels.
However, it is overridden by any driver.
The buffer enable is an active High 3-state (i.e., an active
Low enable), as shown in Table 11.
Three-State Buffer Example
Figure 18 shows how to use the 3-state buffers to imple-
ment a multiplexer. The selection is accomplished by the
buffer 3-state signal.
Pay particular attention to the polarity of the T pin when
using these buffers in a design. Active High 3-state (T) is
identical to an active Low output enable, as shown in
