Abstract
A bus driver for driving a differential data bus can be in a dominant data bus state and in a recessive data bus state. In the dominant data bus state, the bus driver connects the first and second single-wire data bus lines to a first and second electrical potential and temporarily does not drive the first and second single-wire data bus lines in the recessive data bus state. In the recessive data bus state after a change from the dominant data bus state to the recessive data bus state, bus driver connects the first and second single-wire data bus lines to a fourth electrical potential for an active time.
