Abstract: A system is provided for transferring information across a conductor 203. Transmitting circuitry 210 receives information in the form of a first signal having a first voltage swing and, in response, outputs a second signal having a second voltage swing. The first voltage swing is between a first high voltage and a first low voltage and the second voltage swing is between a second high voltage less than the first high voltage and a second low voltage greater than the first low voltage. The second high voltage is substantially equal to a voltage level of a first voltage rail to which the transmitting circuitry 210 is coupled and the second low voltage is substantially equal to a voltage level of a second voltage rail to which the transmitting circuitry 210 is coupled. The conductor 203 carries the second signal output from the transmitting circuitry 210.
