ABSTRACT:
A line buffer circuit for coupling an interface to a data highway without requiring separate signal paths for sense and drive functions, comprises a unity-gain voltage amplifier coupling a line in the highway to the respective interface terminal for the sense function, and a current source connected to sink current from the highway line to ground for the drive function. The current source is controlled so that the current passing through it is proportional to the magnitude of the current passing from the amplifier through the interface terminal.
