SN751177NSR

Drivers, Receivers, Transceivers Overview

The SN751177NSR is a dual differential driver and receiver integrated circuit from the Texas Instruments SN751177 series, designed for RS-422 communication applications. It operates with a nominal supply voltage of 5V, supported by a range of 4.75V to 5.25V. The device features two independent drivers and receivers, supporting a maximum signaling rate of 10 Mbps. It accommodates up to 32 nodes on the bus and provides fault protection within a voltage range of -10V to +15V. The common-mode range extends from -7V to +12V. Packaged in a 16-pin SOIC format, it functions reliably across an operating temperature range of -20°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Dual differential driver and receiver configuration for full-duplex data transmission
• High-speed signaling capability up to 10 Mbps for efficient data transfer
• Robust fault protection against short circuits and line faults
• Wide common-mode voltage range ensuring reliable operation in noisy environments

Drivers, Receivers, Transceivers Applications

• RS-422 balanced digital interface circuits
• Point-to-point or multi-point communication systems
• Industrial control networks requiring high noise immunity

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix NSR confirms the SOIC-16 surface-mount package and tape-and-reel shipping method. Confirm the temperature grade corresponds to the commercial/extended range specifications required for the target application environment. Ensure compatibility with existing PCB footprints and reflow soldering profiles during procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dual-channel RS-422 transceiver is needed with extended temperature capabilities down to -20°C. Compare against the SN751178 if a narrower temperature range is acceptable, as both share similar electrical characteristics. Ensure the design supports the 5V logic levels and that the 10 Mbps data rate meets system throughput requirements without necessitating faster alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN751177 family of dual differential drivers and receivers. It serves as a surface-mount variant of the through-hole SN751177N. The series is engineered for robust communication in industrial settings, offering standard RS-422 performance with enhanced thermal resilience compared to basic commercial variants.

Drivers, Receivers, Transceivers Replacement Considerations

The SN751178 is a functional equivalent within the same family, sharing identical pinouts and electrical specifications. Verify that the SN751178's available temperature grades align with the project's environmental constraints before substitution.
