Abstract
According to the present invention, a first circuit is used to detect a positive voltage transition on a signal line. A second circuit is used to detect a negative voltage transition on the signal line. Upon detecting a transition, the first circuit will drive the signal line high. The second circuit pulls the line to ground after sensing a negative voltage transition. A delay circuit determines the time period in which the first or second circuit is connected to the signal line.
