32-BIT DUAL-SUPPLY BUS TRANSCEIVER

WITH CONFIGURABLE VOLTAGE TRANSLATION AND 3-STATE OUTPUTS

SCES550B – FEBRUARY 2004 – REVISED JUNE 2005

The DOC™ circuitry 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

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.
