output description

The DOC

 circuitry is implemented, which, during the transition, initially lowers the output impedance to

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.
