Abstract

A bus termination circuit actively switches a terminating resistor from the bus conductor in response to a control signal. A first state of the control signal connects the bus conductor through the terminating resistor to a voltage reference source, while a second state of the control signal isolates the bus conductor from the voltage reference source. Thus, the switchable active bus termination circuit can be permanently installed in computer peripheral devices and activated by the control signal.
