ABSTRACT:
A mixed-mode multi-protocol serial interface driver is presented. The driver operates in current-mode, voltage-mode, or both, and includes circuitry for conforming output signals to one of a plurality of selectable electrical interface standards, including, for example, CCITT/EIA standards V.35, V.11/RS-422, V.28/RS-232, and V.10/RS-423. A mode-select input signal selects a particular standard, and appropriate portions of the circuitry are enabled in response. Portions of the circuitry not enabled are placed in a high impedance state to prevent their interference with the enabled portions.
