ISO3082DW Equivalent & Substitute Parts

Part Overview

The ISO3082DW is a 2/2 transceiver with isolated half-duplex RS422/RS485 interface functionality in a 16-SOIC surface mount package. Manufactured by Texas Instruments, this component operates across a 3.15V to 5.5V supply range with a 200kbps data rate and supports operating temperatures from -40°C to 85°C. The device is currently in Last Time Buy status, making identification of active equivalent and substitute parts essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ISO3082DW is determined by the following critical parameters:

• Package compatibility: 16-SOIC (0.295", 7.50mm Width) surface mount form factor
• Protocol support: RS422/RS485 interface standards
• Electrical specifications: Operating voltage range (minimum 3.15V to 5.5V), operating temperature range (-40°C to 85°C)
• Functional configuration: 2/2 driver/receiver topology with half-duplex operation
• Compliance: ROHS3 compliance and EAR99 classification

The substitute parts listed below meet these core substitution criteria. ISO3082DWR is the direct manufacturer equivalent from Texas Instruments in alternative packaging. The MAX14948 and MAX14949 series from Analog Devices Inc./Maxim Integrated provide functional alternatives with enhanced isolation specifications and higher data rates, maintaining package and protocol compatibility.

Parameter Comparison

Engineering Selection Recommendations

ISO3082DWR is the manufacturer-recommended direct equivalent from Texas Instruments, maintaining identical electrical specifications and performance characteristics while offering Active product status. This part is suitable for direct replacement in existing designs with no circuit modifications required.

MAX14948EWE+ and MAX14948EWE+T are functionally compatible alternatives from Analog Devices Inc./Maxim Integrated. These parts support higher data rates (500kbps versus 200kbps) and provide enhanced isolation voltage (5000Vrms). The primary design consideration is the channel configuration difference: MAX14948 devices feature 3 channels with 2/1 input/output configuration versus the ISO3082DW's 2/2 topology. Both variants maintain Active product status and ROHS3 compliance. The EWE+T variant is supplied in Tape & Reel packaging with higher inventory availability.

MAX14949EWE+T offers similar isolation and data rate performance to the MAX14948 series with Active product status. Supply voltage range begins at 3V (versus 1.71V for MAX14948), aligning more closely with the ISO3082DW's 3.15V minimum specification.

All substitute parts maintain the 16-SOIC package footprint, surface mount mounting type, -40°C to 85°C operating temperature range, and ROHS3/EAR99 compliance required for direct substitution consideration.

Frequently Asked Questions (FAQ)

Q: Can ISO3082DWR be used as a direct replacement for ISO3082DW?

A: Yes. ISO3082DWR is the manufacturer-recommended equivalent from Texas Instruments with identical electrical specifications, operating parameters, and 16-SOIC package. The only difference is packaging format (Cut Tape & Digi-Reel versus Tube). No circuit modifications are required.

Q: What are the key differences between ISO3082DW and MAX14948/MAX14949 devices?

A: The primary differences are channel configuration and data rate. ISO3082DW provides 2/2 driver/receiver configuration at 200kbps, while MAX14948 and MAX14949 devices provide 3-channel digital isolators with 2/1 configuration at 500kbps. MAX14948/MAX14949 devices use capacitive coupling isolation technology with 5000Vrms isolation voltage, compared to the ISO3082DW's transceiver architecture. Both support RS422/RS485 protocols and maintain the same 16-SOIC package footprint.

Q: Are the MAX14948 and MAX14949 series interchangeable?

A: MAX14948EWE+ and MAX14948EWE+T are functionally identical, differing only in packaging (Tube versus Tape & Reel). MAX14949EWE+T has a minimum supply voltage of 3V versus 1.71V for MAX14948 variants, making it more compatible with the ISO3082DW's 3.15V minimum specification. All three maintain identical data rates, isolation voltage, and operating temperature ranges.

Q: What packaging options are available for these substitute parts?

A: ISO3082DW is supplied in Tube packaging. ISO3082DWR is available in Cut Tape & Digi-Reel format. MAX14948EWE+ is supplied in Tube, while MAX14948EWE+T and MAX14949EWE+T are supplied in Tape & Reel packaging. All parts use the same 16-SOIC (0.295", 7.50mm Width) surface mount package footprint.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All listed substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes, matching the ISO3082DW compliance profile.
