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 V vs I and V  
vs I  
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.
