Substitute Part Grouping Explanation

Substitution for the DS26LS32ACM is determined by the following critical parameters:

Package compatibility: 16-SOIC form factor with identical 0.154" width and 3.90mm dimensions
Functional equivalence: 0/4 receiver configuration supporting RS422 protocol
Electrical interface: Surface mount technology with compatible pin assignments
Supply voltage range: Parts must operate within or encompass the 4.5V to 5.5V specification
Operating temperature range: Minimum 0°C to 70°C coverage required

The substitute parts identified are grouped by manufacturer and product status. All candidates maintain the 16-SOIC package and 0/4 receiver configuration. Voltage supply ranges and temperature specifications vary among substitutes, requiring verification against specific application requirements.

Engineering Selection Recommendations

All substitute parts maintain the 16-SOIC package form factor and 0/4 receiver configuration required for functional equivalence. The primary differentiators are product status and compliance certifications.

The MAX3096 series (MAX3096CSE+, MAX3096CSE+T, MAX3096ESE+, MAX3096ESE+T) from Analog Devices Inc./Maxim Integrated are active products with ROHS3 compliance. The MAX3096ESE+ and MAX3096ESE+T variants offer extended operating temperature range (-40°C to 85°C) compared to the CSE variants (0°C to 70°C). The ESE+T variant provides the highest inventory availability at 37,800 pieces.

The SP26LV432CN-L from MaxLinear, Inc. is classified as Last Time Buy with ROHS3 compliance. This part offers the highest data rate specification at 50 Mbps.

All substitute parts operate at lower supply voltages (3V to 3.6V or 3.3V) compared to the original DS26LS32ACM (4.5V to 5.5V). Application circuits must accommodate this voltage difference through appropriate power supply design or voltage regulation.

Frequently Asked Questions (FAQ)

Q: Can the MAX3096 series directly replace the DS26LS32ACM without circuit modifications?

A: The MAX3096 series maintains the 16-SOIC package and 0/4 receiver configuration. However, the supply voltage requirement differs significantly: MAX3096 parts operate at 3V to 3.6V, while the DS26LS32ACM requires 4.5V to 5.5V. Circuit power supply design must be modified to accommodate this voltage difference.

Q: What is the significance of the receiver hysteresis difference between the DS26LS32ACM (100 mV) and substitute parts (45 mV to 60 mV)?

A: Receiver hysteresis affects noise immunity and signal transition characteristics. Lower hysteresis values in substitute parts provide tighter input thresholds. Application-specific signal integrity analysis is required to determine compatibility with existing signal conditioning circuits.

Q: Why do the MAX3096ESE+ and MAX3096ESE+T variants have different operating temperature ranges than the CSE variants?

A: The ESE variants are specified for -40°C to 85°C operation, while CSE variants are limited to 0°C to 70°C. The ESE variants are suitable for extended temperature applications. Both variants are functionally equivalent in the 0°C to 70°C range.

Q: What is the difference between MAX3096CSE+T and MAX3096ESE+T packaging?

A: Both use Cut Tape (CT) & Digi-Reel® packaging. The primary difference is the operating temperature specification: CSE+T is rated 0°C to 70°C, while ESE+T is rated -40°C to 85°C. Inventory availability also differs, with ESE+T at 37,800 pieces versus CSE+T at 8,546 pieces.

Q: Is the SP26LV432CN-L suitable for high-speed applications?

A: The SP26LV432CN-L specifies a 50 Mbps data rate, compared to 10 Mbps for the MAX3096 series. However, SP26LV432CN-L is classified as Last Time Buy, indicating limited future availability. For new designs requiring high-speed operation, the MAX3096 series with active product status is recommended.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant. The original DS26LS32ACM is RoHS non-compliant, making the substitute parts suitable for applications with RoHS compliance requirements.
