SN75174N (TEXAS INSTRUMENTS)

The SN75174N is a 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 4megabaud. Driver features wide positive and negative common-mode output voltage ranges making it suitable for party-line applications in noisy environments. It 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°C.
