Overview
The SN75172N is a quadruple monolithic differential line driver designed by Texas Instruments. It meets or exceeds the requirements of ANSI standards EIA/TIA-422-B and RS-485, as well as the ITU recommendation V.11. This device is optimized for balanced multipoint bus transmission at rates of up to 4 megabaud and is particularly suited for party-line applications in noisy environments. Each driver features wide positive and negative common-mode output voltage ranges and includes protective features such as positive- and negative-current limiting and thermal shutdown to protect against line fault conditions.
