【概要】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°C. This device offers optimum performance when used with the SN75173 or SN75175 quadruple differential line receivers. The SN75174 is characterized for operation from 0°C to 70°C. Meets or Exceeds the Requirements of ANSI Standards EIA/TIA-422-B and RS-485 and ITU Recommendation V.11.Designed for Multipoint Transmission on Long Bus Lines in Noisy Environments3-State OutputsCommon-Mode Output Voltage Range of -7 V to 12 VActive-High EnableThermal Shutdown ProtectionPositive- and Negative-Current LimitingOperates From Single 5-V SupplyLow Power RequirementsFunctionally Interchangeable With MC3487【主な仕様】
