SN75112D Equivalent & Substitute Parts

Part Overview

The SN75112D is a 2/0 Driver IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component is classified as an Interface driver with a supply voltage range of 4.75V to 5.25V and an operating temperature range of 0°C to 70°C. The product status is Obsolete, making identification of suitable substitute components necessary for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75112D is based on the following critical parameters:

• Interface Category: Both main and substitute parts must function as Interface components
• Mounting Type: Surface mount compatibility is required
• Supply Voltage Compatibility: Operating voltage ranges must overlap or encompass the original specification
• Temperature Operating Range: Substitute parts must support the required thermal environment
• RoHS and Compliance Status: Regulatory compliance must be maintained or exceeded
• Moisture Sensitivity: MSL rating must be equivalent or superior

The SN65C1167ENSR qualifies as a substitute based on these criteria. While it functions as a Transceiver (2/2 configuration with RS422/RS485 protocol support) rather than a simple Driver, it operates within compatible voltage and temperature parameters and maintains equivalent compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is an Active product from Texas Instruments, providing design continuity for applications requiring the SN75112D. Both components maintain ROHS3 compliance and MSL 1 ratings, ensuring equivalent environmental and regulatory standards.

The substitute part operates across an expanded voltage range (4.5V to 5.5V versus 4.75V to 5.25V) and an extended temperature range (-40°C to 85°C versus 0°C to 70°C), providing broader operational flexibility. The package footprint increases from 14-SOIC to 16-SOIC, requiring PCB layout verification.

Selection of the SN65C1167ENSR is supported by its Active product status, ensuring long-term availability and supply chain stability compared to the Obsolete SN75112D.

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75112D without circuit modifications?

A: The SN65C1167ENSR is functionally compatible within the specified voltage and temperature parameters. However, the package footprint differs (16-SOIC versus 14-SOIC), requiring PCB layout changes. Circuit-level compatibility depends on application-specific signal requirements.

Q: What is the primary difference between these two parts?

A: The SN75112D is a 2/0 Driver, while the SN65C1167ENSR is a 2/2 Transceiver with RS422/RS485 protocol support. The substitute provides bidirectional communication capability and receiver functionality not present in the original part.

Q: Are both parts RoHS compliant?

A: Both the SN75112D and SN65C1167ENSR are ROHS3 compliant with MSL 1 ratings, meeting equivalent environmental standards.

Q: What are the package considerations for substitution?

A: The SN75112D uses a 14-SOIC package (0.154" width), while the SN65C1167ENSR uses a 16-SOIC package (0.209" width). PCB footprint redesign is necessary for physical compatibility.

Q: Is the SN65C1167ENSR available in production quantities?

A: The SN65C1167ENSR maintains Active product status with documented inventory availability, ensuring supply chain continuity compared to the Obsolete SN75112D.
