DESCRIPTION

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 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
