Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS26LS32ACMX is determined by the following critical parameters that must align across candidate parts:

Mechanical Compatibility:

• Package type: 16-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Pin count and footprint equivalence

Functional Compatibility:

• Receiver configuration: 0/4 (zero drivers, four receivers)
• Protocol support: RS422 compatibility (primary requirement)
• Receiver hysteresis characteristics

Electrical Compatibility:

• Supply voltage range overlap or compatibility
• Operating temperature range suitability
• Data rate specifications

All substitute parts listed below maintain the 16-SOIC package format and 0/4 receiver configuration. The MAX3096 series from Analog Devices Inc./Maxim Integrated provides functional equivalence with RS422 and RS485 protocol support, meeting the core receiver requirements of the DS26LS32ACMX.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DS26LS32ACMX is classified as obsolete. All substitute parts in the MAX3096 series are active products with ongoing manufacturer support, ensuring long-term availability and supply chain stability.

Compliance and Certification: All MAX3096 substitute parts are ROHS3 compliant, whereas the DS26LS32ACMX is RoHS non-compliant. For applications requiring regulatory compliance with modern environmental standards, the MAX3096 series provides certified alternatives. Both the original part and all substitutes maintain REACH Unaffected status and EAR99 export classification.

Temperature Range Selection:

• MAX3096CSE+ and MAX3096CSE+T: Operate within 0°C to 70°C, matching the original DS26LS32ACMX operating temperature range. These variants are suitable for applications with standard industrial temperature requirements.
• MAX3096ESE+ and MAX3096ESE+T: Operate within -40°C to 85°C, providing extended temperature range capability. These variants are appropriate for applications requiring broader environmental tolerance or military/aerospace specifications.

Packaging Format Selection:

• Tube packaging (MAX3096CSE+, MAX3096ESE+): Suitable for lower-volume applications and manual assembly processes.
• Cut Tape & Digi-Reel® packaging (MAX3096CSE+T, MAX3096ESE+T): Optimized for high-volume automated assembly operations. The MAX3096ESE+T variant offers the highest inventory availability at 37,800 pieces.

Supply Voltage Consideration: The DS26LS32ACMX operates at 4.5V to 5.5V, while all MAX3096 substitutes operate at 3V to 3.6V. Circuit design modifications may be required to accommodate this voltage difference. Verify that the application's power supply architecture can support the lower voltage range of the substitute parts.

Frequently Asked Questions (FAQ)

Q: Can the MAX3096 series directly replace the DS26LS32ACMX without circuit modifications?

A: The MAX3096 series maintains identical 16-SOIC package geometry and 0/4 receiver configuration, enabling direct pin-compatible substitution. However, the supply voltage range differs (3V to 3.6V for MAX3096 versus 4.5V to 5.5V for DS26LS32ACMX). Circuit design review is required to confirm compatibility with the application's power supply architecture.

Q: What is the significance of the receiver hysteresis difference between the DS26LS32ACMX (100 mV) and MAX3096 series (45 mV)?

A: Receiver hysteresis defines the voltage differential required between the rising and falling threshold levels. The MAX3096 series exhibits lower hysteresis (45 mV), which provides improved noise immunity in certain applications but may require signal conditioning in systems designed for the higher hysteresis (100 mV) of the original part. Signal integrity analysis is recommended for noise-sensitive applications.

Q: Which MAX3096 variant should be selected for new production designs?

A: For new production designs, the MAX3096ESE+T variant is recommended based on active product status, ROHS3 compliance, extended temperature range (-40°C to 85°C), and highest inventory availability (37,800 pieces). The Cut Tape & Digi-Reel® packaging format is optimized for automated assembly processes.

Q: Are all MAX3096 variants electrically interchangeable?

A: All MAX3096 variants (CSE+, CSE+T, ESE+, ESE+T) share identical electrical specifications and pin configurations. The differences are limited to operating temperature range and packaging format. Selection should be based on application temperature requirements and assembly process requirements.

Q: What is the impact of RS485 protocol support in the MAX3096 series compared to RS423 support in the DS26LS32ACMX?

A: The MAX3096 series supports both RS422 and RS485 protocols, providing broader protocol compatibility. RS422 functionality is maintained, ensuring compatibility with existing RS422 system designs. The additional RS485 support does not affect RS422 operation and provides flexibility for future protocol requirements.

Q: How does the 10 Mbps data rate specification of the MAX3096 series compare to the DS26LS32ACMX?

A: The DS26LS32ACMX does not specify a data rate parameter. The MAX3096 series specifies 10 Mbps capability, indicating the maximum supported serial communication speed. For applications operating below 10 Mbps, the MAX3096 series is fully compatible. Applications requiring higher data rates require separate evaluation.

Q: What packaging considerations apply when transitioning from DS26LS32ACMX to MAX3096 variants?

A: The DS26LS32ACMX is supplied in Tape & Reel (TR) format. MAX3096 substitutes are available in Tube (CSE+, ESE+) or Cut Tape & Digi-Reel® (CSE+T, ESE+T) formats. Tube packaging is suitable for lower-volume or manual assembly processes. Cut Tape & Digi-Reel® packaging is optimized for high-volume automated pick-and-place assembly. Verify compatibility with existing assembly equipment and processes.
