The DOC™ circuitry 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 V

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.
