Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LS32ACNS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Package / Case: 16-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount
• Number of Drivers/Receivers: 0/4
• Receiver Hysteresis: 50 mV
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: 0°C ~ 70°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Protocol Compatibility: The AM26LS32ACNS supports RS422 and RS485 protocols. Substitute parts must support at least one of these protocols to maintain functional compatibility within the application circuit.

The AM26LS32ACNSR qualifies as a direct substitute based on full alignment with all mandatory parameters and protocol support (RS422, RS423).

Parameter Comparison

Engineering Selection Recommendations

AM26LS32ACNSR is the qualified substitute for AM26LS32ACNS based on the following engineering criteria:

Compliance & Certification Alignment: Both parts maintain ROHS3 compliance and identical Moisture Sensitivity Level (MSL 1), ensuring regulatory and environmental compatibility across manufacturing and deployment phases.

Product Status Consideration: The AM26LS32ACNS carries Last Time Buy status, indicating end-of-life production. The AM26LS32ACNSR maintains Active product status with current manufacturing support, providing supply chain continuity and long-term availability for new designs and system maintenance.

Electrical Parameter Equivalence: All critical electrical parameters—supply voltage range (4.75V ~ 5.25V), receiver hysteresis (50 mV), and operating temperature range (0°C ~ 70°C)—are identical between both parts, ensuring drop-in compatibility at the circuit level.

Package & Mounting Compatibility: Both components utilize the 16-SOIC package with identical physical dimensions (0.209", 5.30mm Width) and surface mount technology, allowing direct PCB layout reuse without redesign.

Frequently Asked Questions (FAQ)

Q: Can AM26LS32ACNSR directly replace AM26LS32ACNS in existing designs?

A: Yes. Both parts share identical electrical specifications, package dimensions, and mounting technology. No circuit modifications or PCB redesign are required for substitution.

Q: What is the difference between RS422 and RS423 protocol support?

A: The AM26LS32ACNS supports RS422 and RS485 protocols. The AM26LS32ACNSR supports RS422 and RS423 protocols. Both parts support RS422, which is the common protocol in this product family. Protocol selection depends on application requirements.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in 16-SOIC packages with identical physical dimensions. The AM26LS32ACNSR offers additional packaging options (Cut Tape and Digi-Reel®) for procurement flexibility, while the AM26LS32ACNS packaging specification is not detailed in available data.

Q: Why is AM26LS32ACNS marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this specific part number. The AM26LS32ACNSR, with Active status, represents the current production equivalent and is recommended for new designs and ongoing procurement.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), meeting identical environmental and regulatory requirements for manufacturing and field deployment.

Q: What is the base product number for these parts?

A: The base product number is AM26LS32, which encompasses multiple variants including both the AM26LS32ACNS and AM26LS32ACNSR. Suffix variations indicate packaging and product status differences.
