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