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

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 the TI application reports,
