Abstract

A CMOS driver circuit is configured to provide a tri-state condition after a predetermined number of like-valued data bits have been transmitted, reducing the presence of intersymbol interference (ISI) along a transmission channel. In situations where the transmission channel is bandwidth-limited, the use of the tri-stating technique allows for the complete transition to the supply rails during the given bit period.
