Transmission Line Drivers and Receivers for TIA/EIA Standards RS-422 and RS-423 Transmission Line Drivers and Receivers for TIA/EIA Standards RS-422 and RS-423 Introduction With the advent of the microprocessor, logic designs have bee both sophisticated and modular in concept. Frequently the modules making up the system are very closely coupled on a single printed circuit board or cardfile. In a majority of these cases a standard bus transceiver will be adequate. However because of the distributed intelligence ability of the microprocessor, it is being mon practice for the peripheral circuits to be physically separated from the host processor with data munications being...
