SN65HVD76D

Drivers, Receivers, Transceivers Overview

The SN65HVD76D is a 3.3V full-duplex RS-485 transceiver manufactured by Texas Instruments, designed for high-speed data communication in noisy environments. It supports data rates up to 50Mbps and features robust 12kV IEC ESD protection on the bus pins, ensuring reliability in industrial applications. The device operates within an extended temperature range of -40°C to +125°C, making it suitable for harsh conditions. Packaged in a compact 10-pin VSSOP (DGSR suffix variant) or SOIC package, it integrates differential drivers and receivers compliant with EIA-485 standards. Key electrical characteristics include low power consumption and fail-safe receiver inputs that default to a logic-high state when the bus is open.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex operation enabling simultaneous transmission and reception over differential pairs
• High electromagnetic immunity with integrated 12kV IEC ESD protection on bus lines
• Fail-safe receiver design ensures a defined high logic state during idle or fault conditions
• Extended thermal stability supporting reliable performance in extreme ambient temperatures

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring robust fieldbus connectivity
• Building automation networks such as HVAC and lighting control interfaces
• Medical equipment communication modules needing high ESD resilience
• Data acquisition systems operating in electrically noisy environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package suffix against the required footprint, as variants like DGSR indicate VSSOP packaging while others may use SOIC. Confirm RoHS compliance status and lead time requirements directly with authorized distributors, as manufacturing lead times can vary based on production schedules. Ensure the ordering part number matches the exact pin configuration and thermal grade needed for the target application board design.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex communication is required alongside high-speed data transfer capabilities up to 50Mbps. It is appropriate for designs demanding superior ESD protection compared to standard RS-485 devices. Consider the 3.3V supply voltage compatibility with modern microcontrollers. Evaluate the package size constraints, as the VSSOP option offers a smaller footprint than traditional SOIC packages for space-sensitive PCB layouts.

Drivers, Receivers, Transceivers Part Context

This device belongs to the SN65HVD series of high-speed RS-485/RS-422 transceivers from Texas Instruments. It complements other members like the SN65HVD178x series but distinguishes itself through its specific combination of 50Mbps speed and 12kV ESD rating. The family focuses on providing robust interface solutions for industrial protocols where signal integrity and noise immunity are critical parameters for system reliability.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN65HVD75 for half-duplex applications with similar electrical characteristics. For full-duplex needs, the SN65HVD32 serves as a compatible alternative with shutdown functionality. Verify pin-to-pin compatibility and ensure that the replacement part meets the same 12kV ESD protection and 50Mbps data rate specifications required by the original design.
