Abstract
An improved CMOS driver circuit for driving a fast, single-ended, wired-or bus architecture. The driver circuit provides a user-selectable active deassertion assist feature which assists a passive terminator circuit in quickly pulling-up a data or control bus line. The resulting driver circuit provides greater noise immunity to negative voltage transients that result from impedance mismatches caused by poor cable design configurations.
