ABSTRACT:
An interface between two or more integrated circuit devices employs isolation techniques to provide electrical isolation of a digital signal for transmission of the digital signal between a master device and one or more slave devices. Unidirectional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended direction is performed by direction control logic. Logic that monitors read and write transactions operates to determine a desired direction of the digital signal and accordingly directs the digital signal through an appropriate isolator channel.
