Isolation and transmission of digital signals in intended direction

One or more integrated circuit device having a process embodied in said integrated circuit device, said process performing a method of communicating and isolating a digital signal across an interface between a master device and a plurality of slave devices, the method comprising:

• receiving the digital signal at the interface;
• analyzing the digital signal to determine an occurrence of a read or a write transaction to determine an intended direction of the digital signal;
• upon determining an occurrence of a read transaction, transmitting the digital signal from one of the plurality of slave devices to an isolation channel configured to isolate the digital signal in the intended direction
• isolating the digital signal at the isolation channel;
• and
• transmitting the isolated digital signal in the intended direction of the digital signal to the master device.

An isolator component for communicating and electrically isolating a digital signal between a master device and a plurality of slave devices, the isolator component comprising:

• bi-directional communication ports for transmitting and receiving the digital signal between the devices;
• direction detection/control logic for determining an intended direction of the digital signal by monitoring an occurrence of a read or a write transaction;
• and
• uni-directional isolator channels for isolating the digital signal upon determination of the intended direction of the digital signal, wherein the direction detection/control logic transmits the digital signal to an isolator channel configured to operate in the intended direction of the digital signal.
