Registered Bus Exchanger 1-Element 56-Pin TSSOP T/R

A Dynamic Output Control (DOC) circuit is implemented, which, during the transition, initially lowers the outputimpedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1shows typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of thecircuit. At the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that isequivalent to a high-drive standard-output device. For more information, refer to the TI application reports, AVCLogic Family Technology and Applications, literature number SCEA006, and Dynamic Output Control (DOC?)Circuitry Technology and Applications, literature number SCEA009.
