SN75110ADR Equivalent & Substitute Parts

Part Overview

The SN75110ADR is a 2/0 Driver interface IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as Obsolete, indicating it is no longer in active production. The SN75110ADR operates within a supply voltage range of 4.75V to 5.25V and is rated for operating temperatures from 0°C to 70°C. Due to its obsolete status, identifying functionally compatible substitute components is essential for ongoing system maintenance, redesign efforts, and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75110ADR is determined by the following critical parameters:

• Interface Category: Both main and substitute parts must belong to the Interface category for signal conditioning and transmission applications.
• Mounting Type: Surface mount compatibility is required for PCB assembly consistency.
• Supply Voltage Compatibility: The substitute must operate within or encompass the 4.75V to 5.25V supply range of the original part.
• RoHS and Compliance Status: Both parts must maintain ROHS3 compliance and REACH unaffected status for regulatory alignment.
• Moisture Sensitivity Level: MSL 1 rating ensures unlimited shelf life compatibility.

The SN65C1167ENSR qualifies as a manufacturer-recommended substitute. While it functions as a Transceiver (2/2 configuration with Full Duplex) rather than a Driver (2/0 configuration), it operates within compatible voltage ranges (4.5V to 5.5V encompasses the original specification) and maintains equivalent compliance certifications. The substitute provides enhanced functionality with RS422 and RS485 protocol support and an extended operating temperature range (-40°C to 85°C).

Engineering Selection Recommendations

The SN65C1167ENSR is designated as the manufacturer-recommended substitute for the obsolete SN75110ADR. Selection of this substitute is supported by the following engineering criteria:

• Product Status Alignment: The substitute maintains Active product status, ensuring ongoing availability and manufacturer support, contrasting with the Obsolete status of the original part.
• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification.
• Certification Equivalence: Identical MSL 1 ratings and ECCN/HTSUS classifications confirm equivalent handling and logistics compatibility.
• Voltage Supply Compatibility: The substitute's 4.5V to 5.5V supply range encompasses the original 4.75V to 5.25V specification, ensuring direct voltage rail compatibility.
• Surface Mount Packaging: Both components utilize surface mount technology, maintaining assembly process compatibility.

The primary design consideration is the package footprint change from 14-SOIC to 16-SOIC, which requires PCB layout modification. The functional upgrade from Driver (2/0) to Transceiver (2/2) with Full Duplex capability and RS422/RS485 protocol support provides enhanced system flexibility.

Frequently Asked Questions (FAQ)

Q: Why is the SN75110ADR classified as Obsolete?

A: The SN75110ADR has reached end-of-life status in Texas Instruments' product portfolio. Obsolete classification indicates the manufacturer no longer produces this component, making substitute identification necessary for new designs and system maintenance.

Q: Can the SN65C1167ENSR directly replace the SN75110ADR without circuit modification?

A: The SN65C1167ENSR is functionally compatible but requires PCB layout modification due to package size change (14-SOIC to 16-SOIC). The substitute's enhanced transceiver functionality (2/2 configuration versus 2/0 driver) may require circuit design evaluation to utilize bidirectional capabilities.

Q: What is the significance of the voltage supply range difference?

A: The SN65C1167ENSR operates at 4.5V to 5.5V, which encompasses the original SN75110ADR specification of 4.75V to 5.25V. This overlap ensures the substitute functions correctly across the original part's intended supply voltage window.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: The SN65C1167ENSR's extended range (-40°C to 85°C) exceeds the original part's specification (0°C to 70°C). This provides enhanced thermal performance and is not a compatibility limitation; systems designed for the original temperature range operate within the substitute's qualified range.

Q: Are there package footprint considerations for PCB redesign?

A: Yes. The 14-SOIC (3.90mm width) original package differs from the 16-SOIC (5.30mm width) substitute. PCB layout modification is required, including updated land patterns, trace routing, and component placement verification.

Q: What compliance certifications apply to both components?

A: Both the SN75110ADR and SN65C1167ENSR maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings. These certifications ensure equivalent regulatory and environmental compliance.
