Driver isolating circuit for common bus-type transmission of local area network |
摘要 |
A driver in a transceiver for a common bus-type transmission system of a local area network includes a switching transistor for receiving a transmission data signal from a station and outputting a forward data signal to a bus, a diode for stopping data entry from a bus to the switching transistor, a first data detection circuit for detecting the presence of the transmission data signal, a second data detection circuit for detecting the presence of the forward data signal, a determination circuit for detecting the occurrence of the short circuit of either one of the switching transistor and the diode, and a controller for controlling the conduction between the switching transistor and the bus.
