SN75174DWR

The SN75174 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 device is optimized for balanced multipoint bus transmission at rates 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 SN75174 provides positive - and negative - current limiting and thermal shutdown for protection from line fault conditions on the transmission bus line. Shutdown occurs at a junction temperature of approximately 150℃. This device offers optimum performance when used with the SN75173 or SN75175 quadruple differential line receivers. The SN75174 is characterized for operation from 0℃ to 70℃.
