Bus Line Transceivers are often used in modern electronics to enable the ability to send electrical signals down an electrical line from a transmitter, through a channel interconnect, and then into a receiver on the opposite end of the line. Often it is desired to be able to use that same line to then send a signal back to what was once the transmitter and have it received and understood.

Transceivers make it possible to be able to do just that – transceivers allow for a transmitter and a receiver to exist at the same location on an electrical line or interconnect bus. Traditionally, and even in some cases today, you would only have a group of lines or a bus, that are dedicated for transmitting signals down a line into a receiver. Moreover, a separate bus, or group of lines, for receiving information back. Each bus or groups of lines are unidirectional. By implementing the use of a transceiver one can use half the width of the bus, conserve routing space on a circuit board, and be able to send and receive information in both directions, with the use of transceivers, thus enabling a bidirectional bus.

 Most memory interfaces incorporate the use of transceivers into their systems today.
