Abstract: A bidirectional bus circuit according to the present invention typically includes: (a) a first and a second bus line portion for carrying a bidirectional bus signal, where the first bus line portion has a first and a second end, and the second bus line portion has a third and a fourth end; (b) a bus direction sense line for carrying a bus direction signal; (c) a sensing circuit coupled to the sense line for detecting the bus direction signal; and (d) a driving circuit coupled to the sensing circuit and coupled between the second end of the first bus line portion and the third end of the second bus line portion for driving the first and second bus line portions. According to one embodiment of the present invention, the sensing circuit may include a cross coupled NAND gate latch or a cross coupled NOR gate latch. The driving circuit may include a first buffer circuit for driving the first bus line portion and a second buffer circuit for driving the second bus line portion.
