SN65HVD53D Equivalent & Substitute Parts

Part Overview

The SN65HVD53D is a full-duplex RS422/RS485 transceiver manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This interface IC functions as a 1/1 transceiver, enabling bidirectional communication over RS422 and RS485 protocols at data rates up to 25 Mbps. The SN65HVD53D carries a Last Time Buy status, indicating discontinued production. Identifying equivalent and substitute parts is essential for ongoing system support, design revisions, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN65HVD53D is determined by strict equivalence across the following critical parameters:

• Protocol support (RS422 and RS485 compatibility required)
• Transceiver configuration (1/1 driver/receiver ratio)
• Duplex capability (full-duplex operation)
• Data rate performance (25 Mbps minimum)
• Supply voltage range (4.5V to 5.5V)
• Receiver hysteresis specification (50 mV)
• Operating temperature range (-40°C to 85°C)
• Package and pinout compatibility (14-SOIC form factor)
• Electrical and mechanical parameter alignment

The SN65HVD53DR qualifies as a direct substitute based on identical electrical specifications, protocol support, and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The SN65HVD53DR is the manufacturer-recommended substitute for the SN65HVD53D. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The SN65HVD53D is designated Last Time Buy, while the SN65HVD53DR maintains Active product status, ensuring continued availability and supply chain stability.

Both parts comply with ROHS3 standards and carry REACH Unaffected status, meeting environmental and regulatory requirements. The primary distinction is packaging format: the SN65HVD53D is supplied in Tube packaging, while the SN65HVD53DR is available in Cut Tape and Digi-Reel formats. This difference does not affect electrical performance or functional compatibility.

For new designs and ongoing procurement, the SN65HVD53DR is the appropriate selection due to its Active status and superior supply availability.

Frequently Asked Questions (FAQ)

Q: Can the SN65HVD53DR directly replace the SN65HVD53D in existing designs?

A: Yes. The SN65HVD53DR is electrically and mechanically identical to the SN65HVD53D. Both parts feature the same 14-SOIC package, pinout, electrical specifications, and protocol support. No design modifications are required.

Q: What is the difference between Tube and Cut Tape packaging?

A: Tube packaging supplies components in plastic tubes, typically for lower-volume applications. Cut Tape and Digi-Reel packaging provide components on continuous tape, suitable for automated assembly processes. The electrical and functional performance of the component is identical regardless of packaging format.

Q: Why is the SN65HVD53D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. The SN65HVD53DR, with Active status, is the current production equivalent and recommended for all new applications and future procurement.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the SN65HVD53D and SN65HVD53DR are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is 1 (Unlimited) for both parts, indicating no special handling requirements during storage or assembly.

Q: What are the critical parameters for RS422/RS485 transceiver substitution?

A: Critical parameters include protocol support (RS422 and RS485), transceiver configuration (1/1 driver/receiver), duplex capability (full-duplex), data rate (25 Mbps), supply voltage range (4.5V to 5.5V), receiver hysteresis (50 mV), operating temperature range (-40°C to 85°C), and package compatibility (14-SOIC). All parameters must match for functional equivalence.
