Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26C32INS is determined by strict equivalence across the following critical parameters:

Protocol Compatibility: Both substitute parts maintain RS422 and RS423 protocol support, ensuring functional compatibility in existing circuit designs.

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

Electrical Specifications: Receiver hysteresis of 60 mV, supply voltage range of 4.5V to 5.5V, and operating temperature range of -40°C to 85°C are identical across all parts, ensuring direct electrical substitution.

Package Type: All parts use 16-SOIC surface mount packaging, enabling mechanical compatibility on printed circuit boards.

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

The substitute parts are grouped into two categories: MFR Recommended (same base product number with different packaging) and Similar (alternative base product number with equivalent electrical specifications).

Parameter Comparison

Engineering Selection Recommendations

AM26C32INSR: This part is the MFR recommended substitute for the AM26C32INS. Both parts share the identical base product number (AM26C32) and maintain the same 16-SOIC package dimensions (0.209", 5.30mm width). The AM26C32INSR is in Active product status with higher inventory availability (4688 pcs) compared to the Last Time Buy AM26C32INS (1137 pcs). The primary difference is packaging format: AM26C32INSR is supplied in Cut Tape and Digi-Reel format, while AM26C32INS uses standard packaging. This part is the preferred direct replacement for new designs and production continuity.

DS26C32ATM/NOPB: This part provides functional equivalence with identical electrical specifications and protocol support. The DS26C32ATM/NOPB maintains Active product status and is supplied in Tube packaging. The package width differs (0.154", 3.90mm versus 0.209", 5.30mm), which may require PCB layout verification for footprint compatibility. This part is suitable as an alternative when AM26C32INSR availability is constrained.

Both substitute parts satisfy ROHS3 compliance and MSL Level 1 requirements, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can AM26C32INSR directly replace AM26C32INS on existing PCBs?

A: Yes. Both parts use identical 16-SOIC package dimensions (0.209", 5.30mm width) and maintain the same pinout, electrical specifications, and protocol support. PCB layout and footprint remain unchanged.

Q: What is the difference between AM26C32INS and AM26C32INSR?

A: Both parts are based on the same AM26C32 base product number with identical electrical and functional specifications. The primary difference is packaging format: AM26C32INS uses standard packaging, while AM26C32INSR is supplied in Cut Tape and Digi-Reel format. AM26C32INSR is in Active status with higher inventory availability.

Q: Can DS26C32ATM/NOPB replace AM26C32INS?

A: DS26C32ATM/NOPB provides functional equivalence with identical receiver configuration, protocol support, hysteresis, supply voltage, and operating temperature specifications. However, the package width differs (0.154" versus 0.209"), requiring verification of PCB footprint compatibility before substitution.

Q: Why is AM26C32INS designated as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this specific part number. AM26C32INSR is the recommended active replacement from the same manufacturer.

Q: Are all three parts ROHS3 compliant?

A: Yes. AM26C32INS, AM26C32INSR, and DS26C32ATM/NOPB are all ROHS3 compliant with MSL Level 1 rating, satisfying current environmental and regulatory requirements.

Q: What is the significance of the 60 mV receiver hysteresis specification?

A: The 60 mV receiver hysteresis is a critical parameter that determines the switching threshold differential for RS422/RS423 signal detection. All three parts maintain this identical specification, ensuring equivalent noise immunity and signal integrity in serial communication applications.

Q: Can these parts be used interchangeably in RS422 and RS423 applications?

A: Yes. All three parts support both RS422 and RS423 protocols with identical electrical specifications, enabling direct functional substitution in applications using either protocol.
