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.
