Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LV32CDE4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Type: Receiver
• Number of Drivers/Receivers: 0/4
• Protocol Support: RS422 and/or RS485

Secondary Compatibility Criteria:

• Voltage - Supply range (must encompass or match the 3V ~ 3.6V requirement)
• Receiver Hysteresis (50 mV baseline)
• RoHS3 Compliance
• MSL rating

Substitute parts are grouped into two categories:

Category 1: Texas Instruments AM26LV32 Series (Direct Manufacturer Equivalents)

• AM26LV32CD (Tube packaging, Last Time Buy status)
• AM26LV32IDR (Cut Tape & Digi-Reel packaging, Active status)

These parts share the identical base product number (AM26LV32), protocol support (RS422/RS485), receiver configuration (0/4), and package type (16-SOIC). Voltage supply and operating temperature ranges vary by grade.

Category 2: Texas Instruments DS26C32 Series (Protocol-Compatible Alternatives)

• DS26C32ATM/NOPB (Tube packaging, Active status)
• DS26C32ATMX/NOPB (Cut Tape & Digi-Reel packaging, Active status)

These parts support RS422/RS423 protocols with identical receiver configuration (0/4) and 16-SOIC package. Operating voltage is 4.5V ~ 5.5V, requiring circuit-level voltage compatibility verification.

Category 3: Alternative Manufacturer (MaxLinear)

• SP26LV432CN-L (MaxLinear, Inc., Last Time Buy status)

This part provides RS422/RS485 receiver functionality in 16-SOIC package with 3.3V supply voltage and 50 Mbps data rate specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement (Preferred):

AM26LV32IDR is the recommended primary substitute. It maintains identical electrical specifications (3V ~ 3.6V supply, 50 mV hysteresis, RS422/RS485 protocol support, 0/4 receiver configuration) and 16-SOIC package footprint. The extended operating temperature range (-40°C ~ 85°C) provides broader environmental coverage. Active product status ensures long-term availability and supply chain stability. Cut Tape & Digi-Reel packaging supports both prototype and production volume requirements.

AM26LV32CD serves as a secondary option with identical electrical and thermal specifications to the original AM26LV32CDE4. Tube packaging and Last Time Buy status limit its suitability for new designs requiring extended product lifecycle support.

For Voltage-Compatible Substitution (Circuit Redesign Required):

DS26C32ATMX/NOPB and DS26C32ATM/NOPB are viable alternatives when circuit power supply can accommodate 4.5V ~ 5.5V operation. These parts maintain the 0/4 receiver configuration and 16-SOIC package. The 60 mV receiver hysteresis represents a minor specification variance. Active product status and extended operating temperature range (-40°C ~ 85°C) support demanding applications. DS26C32ATMX/NOPB with Cut Tape & Digi-Reel packaging is preferred for production continuity.

For Alternative Manufacturer Consideration:

SP26LV432CN-L (MaxLinear) provides RS422/RS485 receiver functionality with 3.3V supply voltage and 50 Mbps data rate specification. Last Time Buy status and MSL 2 rating indicate limited future availability. This option is suitable only when MaxLinear component qualification is already established in the design or supply chain.

Frequently Asked Questions (FAQ)

Q: Can AM26LV32IDR be used as a direct replacement for AM26LV32CDE4?

A: Yes. Both parts share identical receiver configuration (0/4), protocol support (RS422/RS485), supply voltage range (3V ~ 3.6V), receiver hysteresis (50 mV), and 16-SOIC package footprint. The extended operating temperature range of AM26LV32IDR (-40°C ~ 85°C versus 0°C ~ 70°C) provides additional environmental margin. No circuit modifications are required.

Q: What is the key difference between AM26LV32 and DS26C32 series parts?

A: The AM26LV32 series operates at 3V ~ 3.6V supply voltage with 50 mV receiver hysteresis and supports RS422/RS485 protocols. The DS26C32 series operates at 4.5V ~ 5.5V supply voltage with 60 mV receiver hysteresis and supports RS422/RS423 protocols. Substitution requires verification that the circuit power supply and protocol requirements are compatible with the DS26C32 specifications.

Q: Is the SP26LV432CN-L from MaxLinear a suitable substitute?

A: SP26LV432CN-L maintains the 0/4 receiver configuration, RS422/RS485 protocol support, and 16-SOIC package. The 3.3V supply voltage is compatible with the original part's 3V ~ 3.6V range. However, Last Time Buy status and MSL 2 rating indicate limited availability. This option is recommended only when MaxLinear components are already qualified in the design.

Q: Why do some substitute parts have different operating temperature ranges?

A: Operating temperature range is determined by the specific product grade and manufacturing process. AM26LV32IDR, DS26C32ATM/NOPB, and DS26C32ATMX/NOPB are industrial-grade parts rated for -40°C ~ 85°C operation, providing broader environmental coverage than the commercial-grade AM26LV32CDE4 (-40°C ~ 70°C). Selection depends on the application's thermal requirements.

Q: What does Last Time Buy status mean for the AM26LV32CDE4?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this part number. No new production is planned after existing inventory is depleted. Immediate substitution planning is necessary for designs requiring long-term component availability. AM26LV32IDR (Active status) is the recommended alternative for new designs and ongoing production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 Compliance status, ensuring compatibility with environmental and regulatory requirements equivalent to the original AM26LV32CDE4.

Q: What is the significance of MSL (Moisture Sensitivity Level) differences?

A: AM26LV32CDE4, AM26LV32CD, AM26LV32IDR, DS26C32ATM/NOPB, and DS26C32ATMX/NOPB are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. SP26LV432CN-L is rated MSL 2 (1 Year), requiring controlled storage conditions and bake-out procedures if storage exceeds one year. This affects supply chain logistics and inventory management practices.
