ABSTRACT:
A split level differential bus having first and second signals at first and second lines, respectively, for transmitting data from a typical driver to a typical receiver, includes a first independent voltage source for terminating the first line and a second independent voltage source for terminating the second line, the second independent voltage source providing a voltage level that is different from the voltage level provided by the first independent voltage source. A current switch circuit controlled by the driver for switching current from the first line to the second line. A level shifting circuit coupled between the first line and the receiver for level shifting the first signal by a predetermined voltage.
