Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LV32CD is determined by the following critical parameters:

Primary Compatibility Criteria:

• Protocol support: RS422 and/or RS485
• Receiver configuration: 0/4 (4 receivers, no drivers)
• Package type: 16-SOIC surface mount
• Supply voltage range: Must accommodate 3V ~ 3.6V operation
• Operating temperature: Must support at least 0°C ~ 70°C
• Receiver hysteresis: 50 mV nominal (±10 mV tolerance acceptable)

Substitution Categories:

Direct Substitutes (Identical Electrical Specifications):

• AM26LV32CDR: Same base part, different packaging (Cut Tape/Digi-Reel)
• AM26LV32IDR: Extended temperature range (-40°C ~ 85°C), Active product status

Compatible Substitutes (Functional Equivalence with Parameter Variations):

• DS26C32ATM/NOPB: RS422/RS423 protocol, 4.5V ~ 5.5V supply, 60 mV hysteresis, Active status
• DS26C32ATMX/NOPB: RS422/RS423 protocol, 4.5V ~ 5.5V supply, 60 mV hysteresis, Active status, Cut Tape packaging
• DS34LV86TM/NOPB: RS422/RS485 protocol, 3V ~ 3.6V supply, 35 mV hysteresis, Active status
• SP26LV432CN-L: RS422/RS485 protocol, 3.3V supply, 60 mV hysteresis, 50 Mbps data rate, Last Time Buy status

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required):

AM26LV32CDR is the primary direct substitute, offering identical electrical specifications with higher inventory availability (42640 Pcs vs. 2260 Pcs). Both parts share Last Time Buy status, indicating similar supply constraints.

For Extended Product Lifecycle:

AM26LV32IDR is the recommended long-term substitute. This part maintains identical electrical specifications (3V ~ 3.6V supply, 50 mV hysteresis, RS422/RS485 protocol) while offering Active product status and extended operating temperature range (-40°C ~ 85°C). Inventory availability is significantly higher (52748 Pcs), supporting sustained production requirements.

For Alternative Supply Chain Options:

DS34LV86TM/NOPB provides functional equivalence with Active product status and extended temperature range. The 35 mV receiver hysteresis is tighter than the 50 mV specification, which may improve noise immunity in certain applications. Supply voltage and protocol compatibility remain identical.

For Legacy System Compatibility:

DS26C32ATM/NOPB and DS26C32ATMX/NOPB are functionally compatible but require system-level voltage supply adjustment (4.5V ~ 5.5V vs. 3V ~ 3.6V). These parts support RS422/RS423 protocols with Active product status and extended temperature range. Use only if system power architecture permits voltage adjustment.

Not Recommended for New Designs:

SP26LV432CN-L carries Last Time Buy status identical to the original part, providing no supply chain advantage. Selection should be limited to applications requiring MaxLinear device qualification.

Frequently Asked Questions (FAQ)

Q: Can AM26LV32CDR be used as a direct drop-in replacement for AM26LV32CD?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: AM26LV32CD is supplied in Tube packaging, while AM26LV32CDR is supplied in Cut Tape (CT) & Digi-Reel format. Pin configuration, electrical performance, and operating specifications are identical.

Q: What is the primary advantage of AM26LV32IDR over AM26LV32CD?

A: AM26LV32IDR maintains identical electrical specifications while offering Active product status (vs. Last Time Buy) and extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C). This ensures long-term availability and supports applications requiring wider temperature operation.

Q: Can DS26C32ATMX/NOPB replace AM26LV32CD without circuit modifications?

A: No. DS26C32ATMX/NOPB requires 4.5V ~ 5.5V supply voltage, while AM26LV32CD operates at 3V ~ 3.6V. System power supply architecture must be modified to accommodate this voltage difference. Additionally, the protocol support differs (RS422/RS423 vs. RS422/RS485).

Q: What does receiver hysteresis mean, and why does it vary among substitutes?

A: Receiver hysteresis defines the voltage difference between the rising and falling threshold levels of the input comparator. Lower hysteresis (35 mV in DS34LV86TM/NOPB) provides tighter threshold control and improved noise immunity. Higher hysteresis (60 mV in DS26C32 and SP26LV432CN-L series) provides greater noise margin but less precise threshold switching. The 50 mV specification of AM26LV32CD represents a balanced design point.

Q: Is the 16-SOIC package identical across all substitute parts?

A: Yes. All listed substitute parts use the 16-SOIC (0.154", 3.90mm Width) surface mount package. PCB footprints and reflow soldering profiles are compatible across all parts listed.

Q: Why is AM26LV32IDR preferred over AM26LV32CDR despite identical specifications?

A: AM26LV32IDR carries Active product status, ensuring manufacturer support and continued availability. AM26LV32CDR, like the original AM26LV32CD, is Last Time Buy, indicating limited future production. For new designs or long-term production runs, Active status provides supply chain security.

Q: Can SP26LV432CN-L be used in applications requiring RS485 protocol?

A: Yes. SP26LV432CN-L supports both RS422 and RS485 protocols, matching the original AM26LV32CD specification. However, this part also carries Last Time Buy status, providing no supply advantage over the original component.

Q: What is the significance of RoHS3 compliance and REACH Unaffected status?

A: All listed parts are ROHS3 Compliant and REACH Unaffected, indicating compliance with European environmental regulations. This ensures compatibility with modern manufacturing standards and regulatory requirements across global markets.
