Patent ID: 7786759

Claim:
A bidirectional signal interface, comprising: a first node operable to receive a first logic signal; a second node operable to receive a second logic signal; a first translating circuit having a first signal path coupled between the first and second nodes, operable to receive an enable signal, operable to sense a transition of the first logic signal on the first node, and, in response to the enable signal and the transition, operable to couple the first logic signal to the second node via the first signal path; and a second translating circuit having a second signal path coupled between the first and second nodes in parallel to the first signal path, the second translating circuit operable to receive the enable signal, operable to sense a transition of the second logic signal on the second node, and, in response to the enable signal and the transition of the second logic signal, operable to couple the second logic signal to the first node via the second signal path.
