Abstract
A driver stage uses a primary driver and a secondary driver to balance drive current when transmitting a new data bit different than bits consecutively transmitted immediately previous to the new data bit. The primary driver activates one of a pull-down device and a pull-up device whenever transmitting a data bit. The secondary driver activates one of its pull-down device and a pull-up device when two or more consecutive are detected to be transmitted. In this case, current flow of the driver stage induced by the first of the consecutive bits is reduced by the secondary driver.
