Abstract
A system for transmitting digital signals over a transmission line including a driver of an inverter employing CMOS FET's and a termination of an inverter employing CMOS FET's. A sense/control circuit at the termination senses changes in the operating condition of the driver inverter and in response thereto controls the operating condition of the termination inverter. Under steady state conditions the termination inverter establishes the appropriate voltage at an output connection coupled thereto without dissipating any power.
