Abstract
A circuit for coupling transitional energy from the output of a transmitting circuit to the input of a receiving circuit in advance of the normal connective path, which contains an inherent circuit time delay. Feed forward compensation circuitry is incorporated into a logic driver having control circuitry for receiving an input bistate data bit and providing power at an output at first and second predetermined voltage levels when an input bistate data bit is respectively of first and second states. The feed forward compensation circuitry is included in the control circuitry for modifying the response time of the control circuitry for providing output power in response to the input bistake data bit. Sensing circuitry is coupled to the control circuitry for detecting the level of current at the output and providing a corresponding current level indication. The logic driver further includes overcurrent circuitry, responsive to the current level indication, for generating an overcurrent command when the output current exceeds a predetermined level. The control circuitry is responsive to the overcurrent command for disabling the output of power at the corresponding predetermined voltage level at the output.
