DESCRIPTION/ORDERING INFORMATION
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 the TI application reports, AVC Logic Family

Technology and Applications, literature number SCEA009.
