AM26C32IDRG4 Equivalent & Substitute Parts

Part Overview

The AM26C32IDRG4 is a 0/4 Receiver RS422/RS423 interface IC manufactured by Texas Instruments in a 16-SOIC package. This component is discontinued at DiGi Electronics, making equivalent and substitute parts necessary for ongoing system support and new designs. The part operates across industrial temperature ranges (-40°C to 85°C) with 4.5V to 5.5V supply voltage, suitable for serial communication applications requiring RS422 or RS423 protocol compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26C32IDRG4 is determined by strict alignment of the following critical parameters:

• Protocol support (RS422, RS423)
• Receiver configuration (0/4 drivers/receivers)
• Receiver hysteresis (60 mV)
• Supply voltage range (4.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (16-SOIC)
• RoHS3 compliance

Substitute parts are grouped into two categories: parametric equivalents (identical electrical and mechanical specifications) and manufacturer-recommended alternatives (functionally compatible with minor parameter variations).

Parameter Comparison

Engineering Selection Recommendations

For direct replacement of the discontinued AM26C32IDRG4, the AM26C32IDR is the primary choice. This part maintains identical electrical specifications and package configuration while offering active product status with 22,800 units in stock. Both parts are Texas Instruments products with ROHS3 compliance and unlimited moisture sensitivity rating.

The DS26C32ATMX/NOPB and DS34C86TMX/NOPB are parametric equivalents from Texas Instruments, also in active status with substantial inventory availability. These parts satisfy all critical substitution parameters and are suitable for new designs or system upgrades.

The ST26C32ABDR from STMicroelectronics provides an alternative from a different manufacturer while maintaining protocol support, receiver configuration, hysteresis, supply voltage, and temperature range specifications. This part is actively produced with 87,600 units available.

The SP26LV432CN-L from MaxLinear is designated as a manufacturer-recommended alternative but operates at 3.3V supply voltage and a reduced temperature range (0°C to 70°C), making it suitable only for applications where these parameter variations are acceptable. This part is in Last Time Buy status.

Frequently Asked Questions (FAQ)

Q: Can AM26C32IDR directly replace AM26C32IDRG4?

A: Yes. Both parts share identical electrical specifications (RS422/RS423 protocol, 0/4 receiver configuration, 60 mV hysteresis, 4.5V–5.5V supply, -40°C to 85°C operating range) and the same 16-SOIC package. The primary difference is product status: AM26C32IDR is active with higher inventory availability.

Q: What is the difference between DS26C32ATMX/NOPB and AM26C32IDR?

A: Both are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the base product number designation (DS26C32 versus AM26C32) and internal architecture, though they are functionally interchangeable for RS422/RS423 receiver applications.

Q: Why is SP26LV432CN-L listed as a substitute if it has different voltage and temperature specifications?

A: SP26LV432CN-L is designated as a manufacturer-recommended alternative rather than a direct equivalent. It maintains the same receiver configuration, hysteresis, and package but operates at 3.3V (not 4.5V–5.5V) and a narrower temperature range (0°C–70°C). Use this part only if your application requirements align with these parameters.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting environmental and regulatory requirements equivalent to the original AM26C32IDRG4.

Q: What is the package compatibility between these parts?

A: All substitute parts use the 16-SOIC (0.154", 3.90mm width) surface-mount package, ensuring PCB footprint compatibility with the original AM26C32IDRG4 design.

Q: Can I use ST26C32ABDR in place of AM26C32IDRG4?

A: Yes. The ST26C32ABDR meets all critical substitution parameters: RS422/RS423 protocol, 0/4 receiver configuration, 60 mV hysteresis, 4.5V–5.5V supply voltage, -40°C to 85°C operating range, and 16-SOIC package. It is actively produced by STMicroelectronics with substantial inventory.
