ABSTRACT:
The direction of a bidirectional buffer inserted along a bus line is dynamically controlled to be always away from the signal source. The signals which select a tristate buffer to turn on for driving the bus also affect or determine the direction of all buffers inserted in the bus line. Since only one tristate enable signal will be active, the direction which each bidirectional buffer should drive is dynamically determined by the presently active enable signal.
