Abstract:
A terminating circuit for a transmission line comprising,a first switching means that is connected between a signal line that is driven at a first voltage level or a second voltage level, and a first voltage supply terminal,a second switching means that is connected between the above-mentioned signal line and a second voltage supply terminal,a first control means that places the above-mentioned first switching means in the conductive state when the above-mentioned signal line is at the above-mentioned first voltage level, and places the above-mentioned second switching means in the conductive state when the above-mentioned signal line is at the second voltage level,a third switching means that is connected between the above-mentioned signal line and the above-mentioned first voltage supply terminal,a fourth switching means that is connected between the above-mentioned signal line and the second voltage supply terminal,and a second control means that places the above-mentioned third switching means temporarily in a conductive state at the time the above-mentioned signal line is shifted from the first voltage level to the second voltage level, and places the above-mentioned fourth switching means temporarily in a conductive state at the time the above-mentioned signal line is shifted from the second voltage level to the first voltage level.
