SN75182N Equivalent & Substitute Parts

Part Overview

The SN75182N is a 0/2 Receiver interface IC manufactured by Texas Instruments in 14-PDIP through-hole packaging. This component operates within a 4.5V to 5.5V supply voltage range and is rated for 0°C to 70°C operating temperatures. The product is classified as obsolete, making identification of functionally compatible alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SN75182N is determined by the following critical parameters:

• Supply voltage compatibility: 4.5V ~ 5.5V range
• Interface category classification
• RoHS3 compliance certification
• Functional receiver capability

The SN65C1167ENSR qualifies as a manufacturer-recommended substitute based on matching supply voltage specifications and RoHS3 compliance status. However, this substitute introduces functional and packaging differences that must be evaluated for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The SN65C1167ENSR is the manufacturer-designated substitute for the obsolete SN75182N. Both components maintain identical supply voltage specifications (4.5V ~ 5.5V) and ROHS3 compliance certification, establishing electrical compatibility at the power supply level.

Selection of the SN65C1167ENSR requires evaluation of the following factors:

• Mounting technology transition from through-hole (14-DIP) to surface-mount (16-SOIC) requires PCB redesign
• Functional upgrade from receiver-only (0/2) to full transceiver (2/2) with RS422/RS485 protocol support
• Extended operating temperature range (-40°C ~ 85°C) provides broader environmental capability
• Active product status ensures ongoing availability and manufacturer support

Frequently Asked Questions (FAQ)

Q: Can the SN65C1167ENSR directly replace the SN75182N in existing designs?

A: Direct pin-for-pin replacement is not possible due to package differences (14-DIP versus 16-SOIC) and pin count variation. PCB redesign is required for implementation.

Q: What are the key electrical compatibility factors?

A: Both components operate within the identical 4.5V to 5.5V supply voltage range and maintain ROHS3 compliance. This establishes core electrical compatibility for power supply integration.

Q: Why does the SN65C1167ENSR have more drivers and receivers than the SN75182N?

A: The SN65C1167ENSR is a full transceiver (2/2 configuration) compared to the receiver-only SN75182N (0/2 configuration). This represents a functional enhancement rather than a limitation, providing bidirectional communication capability.

Q: Are there temperature rating differences between these components?

A: Yes. The SN75182N operates from 0°C to 70°C, while the SN65C1167ENSR operates from -40°C to 85°C. The substitute provides extended temperature range capability suitable for broader environmental applications.

Q: What mounting considerations apply to substitution?

A: The SN75182N uses through-hole mounting (14-DIP package), while the SN65C1167ENSR uses surface-mount technology (16-SOIC package). Manufacturing process and assembly equipment compatibility must be evaluated during design transition.
