AM26C32IDG4 Equivalent & Substitute Parts

Part Overview

The AM26C32IDG4 is a 0/4 Receiver RS422/RS423 interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited future availability. Finding equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain flexibility for applications requiring RS422/RS423 receiver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26C32IDG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Protocol support: RS422 and/or RS423
• Receiver configuration: 0/4 (4 receivers, 0 drivers)
• Receiver hysteresis: 60 mV
• Package type: 16-SOIC surface mount
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

Substitute parts are grouped into two categories:

MFR Recommended Substitutes (Texas Instruments AM26C32 series variants and MaxLinear SP26LV432CN-L): These parts share identical or compatible electrical specifications with the main part, including supply voltage, temperature range, and receiver hysteresis. Packaging variants (Tube vs. Cut Tape) do not affect functional compatibility.

Parametric Equivalents (Texas Instruments DS26C32ATM/NOPB, DS34C86TM/NOPB, and STMicroelectronics ST26C32ABDR): These parts meet the core functional requirements of RS422/RS423 reception with matching receiver hysteresis and package form factor, though they may originate from different base product families.

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

AM26C32IDR, DS26C32ATM/NOPB, DS34C86TM/NOPB, and ST26C32ABDR are all Active products with full supply availability. These parts are recommended for new designs and long-term production requirements. All four maintain identical electrical specifications to the AM26C32IDG4, including 4.5V ~ 5.5V supply voltage, -40°C ~ 85°C operating temperature, and 60 mV receiver hysteresis.

Alternative Consideration (Voltage/Temperature Constraints):

SP26LV432CN-L is a MaxLinear alternative that supports RS422/RS485 protocols with identical receiver hysteresis. However, this part operates at 3.3V supply voltage and 0°C ~ 70°C temperature range, making it suitable only for applications with compatible power and thermal requirements.

Compliance Status:

All substitute parts listed are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards equivalent to the main part.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IDR directly replace AM26C32IDG4?

A: Yes. Both parts are Texas Instruments AM26C32 base products with identical electrical specifications. The difference is packaging format (Tube vs. Cut Tape & Digi-Reel). Functional compatibility is complete.

Q: What is the difference between MFR Recommended and Parametric Equivalent substitutes?

A: MFR Recommended substitutes are direct variants within the same product family (AM26C32 series) or approved cross-manufacturer alternatives. Parametric Equivalents meet the core functional requirements but may originate from different product families (DS26C32, DS34C86, ST26C32).

Q: Is SP26LV432CN-L compatible with my 5V system?

A: No. SP26LV432CN-L operates at 3.3V supply voltage, not 4.5V ~ 5.5V. Use this part only in 3.3V systems. Additionally, its operating temperature range is 0°C ~ 70°C, which is narrower than the AM26C32IDG4.

Q: Do all substitutes support both RS422 and RS423?

A: All listed substitutes support RS422. SP26LV432CN-L supports RS422 and RS485 instead of RS423. For applications requiring RS423 specifically, use AM26C32IDR, DS26C32ATM/NOPB, DS34C86TM/NOPB, or ST26C32ABDR.

Q: Which substitute has the highest inventory availability?

A: ST26C32ABDR has 87,600 pieces in stock, followed by AM26C32IDR with 22,800 pieces. Both are Active products suitable for immediate procurement.

Q: Are there package differences between substitutes?

A: All substitutes use 16-SOIC surface mount packaging with 0.154" (3.90mm) width. Packaging variants (Tube, Cut Tape, Digi-Reel) affect handling and delivery format but not electrical or mechanical compatibility.
