AM26C32CNS Equivalent & Substitute Parts

Part Overview

The AM26C32CNS is a 0/4 Receiver interface IC manufactured by Texas Instruments, designed for RS422 and RS423 serial communication protocols. This component operates as a quad receiver in a 16-SOIC surface mount package with a 60 mV receiver hysteresis specification and 200 kbps data rate capability. The AM26C32CNS is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent and substitute parts is necessary to ensure continued availability for new designs, maintenance applications, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26C32CNS is determined by the following critical parameters:

Protocol Compatibility: Both substitute parts maintain RS422 and RS423 protocol support, ensuring functional equivalence in serial communication applications.

Receiver Configuration: All parts maintain the 0/4 receiver configuration (quad receiver, no drivers), preserving the functional role within the system.

Electrical Specifications: Supply voltage range (4.5V ~ 5.5V) and receiver hysteresis (60 mV) are identical across all parts, ensuring electrical compatibility.

Package Compatibility: The 16-SOIC surface mount package is maintained across substitute parts, with dimensional variations noted in the Parameter Comparison section.

Compliance Standards: All parts maintain ROHS3 compliance and MSL Level 1 rating, meeting environmental and handling requirements.

The AM26C32CNS is classified as Last Time Buy, making the Active-status substitute parts necessary for design continuity and production planning.

Engineering Selection Recommendations

AM26C32INSR is the primary substitute for the AM26C32CNS. This part maintains identical package dimensions (16-SOIC 0.209" width), electrical specifications, and protocol support. The AM26C32INSR carries Active product status, ensuring long-term availability and supply chain stability. Operating temperature range extends to -40°C ~ 85°C, providing broader environmental coverage than the original part. ROHS3 compliance and MSL Level 1 rating are maintained. This part is suitable for direct replacement in applications where the extended temperature range does not create design conflicts.

DS26C32ATM/NOPB is an alternative substitute with identical electrical and protocol specifications. This part features a narrower 16-SOIC package (0.154" width) compared to the AM26C32CNS (0.209" width). The dimensional difference requires PCB layout verification before implementation. DS26C32ATM/NOPB maintains Active product status, ROHS3 compliance, and MSL Level 1 rating. The extended operating temperature range (-40°C ~ 85°C) matches the AM26C32INSR. This part is suitable for applications where PCB space constraints favor the narrower package footprint.

Both substitute parts are manufactured by Texas Instruments and maintain full protocol and electrical compatibility with the AM26C32CNS.

Frequently Asked Questions (FAQ)

Q: Can AM26C32INSR directly replace AM26C32CNS without PCB modifications?

A: Yes. The AM26C32INSR maintains identical package dimensions (16-SOIC 0.209" width), pin configuration, and electrical specifications. No PCB layout changes are required for direct substitution.

Q: What is the difference between AM26C32INSR and DS26C32ATM/NOPB?

A: Both parts maintain identical electrical specifications and protocol support. The primary difference is package width: AM26C32INSR uses 0.209" width, while DS26C32ATM/NOPB uses 0.154" width. PCB footprint compatibility must be verified before selecting DS26C32ATM/NOPB.

Q: Why is the AM26C32CNS classified as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this part number. Substitute parts with Active status (AM26C32INSR and DS26C32ATM/NOPB) are recommended for new designs and ongoing production requirements.

Q: Are the substitute parts compatible with the original operating temperature range?

A: The AM26C32CNS operates at 0°C ~ 70°C. Both substitute parts operate at -40°C ~ 85°C, providing extended temperature coverage. Applications limited to the original 0°C ~ 70°C range remain fully compatible with substitute parts.

Q: Do all parts maintain the same receiver hysteresis specification?

A: Yes. All three parts (AM26C32CNS, AM26C32INSR, and DS26C32ATM/NOPB) maintain 60 mV receiver hysteresis, ensuring identical noise immunity and signal detection characteristics.

Q: What packaging options are available for the substitute parts?

A: AM26C32INSR is available in Cut Tape (CT) and Digi-Reel® packaging. DS26C32ATM/NOPB is available in Tube packaging. Packaging selection depends on production volume and assembly process requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. The AM26C32CNS, AM26C32INSR, and DS26C32ATM/NOPB are all ROHS3 compliant with MSL Level 1 rating, meeting environmental and handling standards.
