ABSTRACT:
A local area network line system having a bus line and a plurality of devices is disclosed. Each of the devices comprises a data receiver circuit coupled to the bus line for detecting a communication start request from a signal applied on the bus line and being in a sleep mode when the data receiver circuit receives a sleep command signal and a transmitting circuit coupled to the bus line for outputting a transmitting signal in response to a transmit control signal. Each of the devices further comprises an edge detection circuit coupled to the bus line for detecting a level variation of the signal applied on the bus line and outputting a detection signal in response to the detected level variation and a communication control circuit coupled to the data receiver circuit, the transmitting circuit and the edge detection circuit for outputting the transmit control signal to the transmitting circuit. The transmitting circuit includes a sleep/wake-up control circuit for outputting the sleep command signal to the data receiver circuit.
