description

A Dynamic Output Control (DOC) circuit is implemented, which, during the transition, initially lowers the output

impedance to effectively drive the load and, subsequently, raises the impedance to reduce noise. Figure 1

shows typical VOL vs IOL and VOH vs IOH curves to illustrate the output impedance and drive capability of the

circuit. At the beginning of the signal transition, the DOC circuit provides a maximum dynamic drive that is

equivalent to a high-drive standard-output device. For more information, refer to TI application reports AVC
