Abstract
A bidirectional data transceiver circuit is described which automatically transfers data from a first bidirectional data port to a second bidirectional data port when new data is detected. The transceiver has a collision arbitration circuit which prevents the device from driving data onto a data port that is being driven externally. An additional embodiment is described wherein the transition detection circuitry of the transceiver is used to provide a input transition detection flag for an integrated circuit having standby or low power modes. An integrated circuit providing an array of the transceivers of the invention is described. A transceiver which automatically detects a transition in data and provides output drive for data busses is described. Other devices, systems and methods are also described.
