Abstract
A data bus circuit connects a south bridge driven by a first voltage and a bay driven by a second voltage. The first voltage and the second voltage are different. The data bus circuit includes a data bus that electrically connects the south bridge and the bay, and a Thevenin termination circuit that is arranged on the data bus at a point. The Thevenin termination circuit maintains a voltage at the point substantially equal to the first voltage.
