SN65HVD54D

Drivers, Receivers, Transceivers Overview

The SN65HVD54D is a high-speed RS-422/RS-485 transceiver manufactured by Texas Instruments. It integrates one driver and one receiver in an SOIC-14 package, supporting data rates up to 50 Mb/s. The device operates on a single 5 V supply with a typical quiescent current of 8 mA. It features fail-safe circuitry to ensure a high logic state when inputs are open. The component supports full-duplex communication and includes thermal shutdown protection. It functions within an industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Supports high-speed data transmission up to 50 Mb/s for demanding industrial applications
• Integrates fail-safe logic to maintain a high output state during input disconnection
• Includes thermal shutdown protection to prevent damage during excessive power dissipation

Drivers, Receivers, Transceivers Applications

• Industrial automation networks requiring robust RS-485 communication
• Building automation systems utilizing high-speed data transfer
• Process control instrumentation with full-duplex requirements

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for the target region. Cross-reference the datasheet revision date to validate electrical characteristics and pinout configurations before integration into the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring full-duplex operation at speeds up to 50 Mb/s. The 5 V supply voltage makes it suitable for legacy systems or interfaces not compatible with 3.3 V logic levels. Consider the SOIC-14 footprint constraints and the -40°C to +85°C operating range when evaluating environmental suitability for the intended application.

Drivers, Receivers, Transceivers Part Context

This part belongs to the SN65HVD family of high-speed differential bus transceivers. It complements other variants like the SN65HVD55 (1 Mb/s) and SN65HVD53 (10 Mb/s) by offering higher bandwidth capabilities. The series is designed for reliable communication in noisy industrial environments, providing standardized RS-422 and RS-485 interface functionality.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include the SN65HVD54DR (tape and reel version) and SN65HVD54DGVR. Verify compatibility with SN65HVD53 or SN65HVD55 if speed adjustments are acceptable, noting differences in maximum data rate specifications.
