Product Summary
The SN75172DWR is a monolithic quadruple differential line driver with 3-state outputs. It is designed to meet the requirements of ANSI Standards EIA/TIA-422-B and RS-485 and ITU Recommendation V.11. The SN75172DWR is optimized for balanced multipoint bus transmission at rates of up to 4 megabaud. Each driver features wide positive and negative common-mode output voltage ranges, making it suitable for party-line applications in noisy environments. The SN75172DWR provides positive- and negative-current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line.
