Abstract
An embodiment of a bidirectional signal interface includes first and second nodes and first and second translating circuits. The first and second nodes are respectively operable to receive a first logic signal and a second logic signal. The first translating circuit has a first signal path coupled between the first and second nodes, is operable to sense a transition of the first logic signal on the first node, and, in response to the transition, is operable to couple the first logic signal to the second node via the first signal path. The second translating circuit has a second signal path that is coupled between the first and second nodes and that is parallel to the first signal path, is operable to sense a transition of the second logic signal on the second node, and is, in response to the transition of the second logic signal, operable to couple the second logic signal to the first node via the second signal path.
