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

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 SCEA006, and Dynamic Output Control (DOC™ ) Circuitry
Technology and Applications, literature number SCEA009.
