Product Summary

  • The SN751177NSR is a DUAL DIFFERENTIAL DRIVER AND RECEIVER. The SN751177NSR receivers are monolithic integrated circuits that are designed for balanced multipoint bus transmission at rates up to 10 Mbit/s. The SN751177NSR is designed to improve the performance of full-duplex data communications over long bus lines and meet ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A and ITU Recommendations V.10 and V.11. The SN751177NSR provides limiting for both positive and negative currents and thermal-shutdown protection from line-fault conditions on the transmission bus line.
