The DOC™ circuitry is implemented, which, during the transition, initially lowers the output impedance to

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.
