Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LS32ACDE4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 16-SOIC surface mount form factor
• Receiver configuration: 0/4 (4 receivers, 0 drivers)
• Protocol support: RS422 and/or RS423 compatibility
• Receiver hysteresis: 50 mV nominal specification
• Supply voltage range: 4.75V to 5.25V operation
• Operating temperature range: 0°C to 70°C minimum
• RoHS3 compliance and MSL rating

Substitute parts are grouped into two categories based on electrical parameter alignment:

Category 1 - Texas Instruments AM26LS32 Series (Direct Substitutes): Parts AM26LS32ACD and AM26LS32ACDR maintain identical electrical specifications, protocol support, and supply voltage requirements as the main part. These represent the closest functional equivalents with full parameter compatibility.

Category 2 - Cross-Manufacturer Alternatives (Conditional Substitutes): Parts from Analog Devices Inc./Maxim Integrated (MAX3096 series) and MaxLinear Inc. (SP26LV432CN-L) provide equivalent receiver functionality and 16-SOIC packaging but operate under different supply voltage ranges and temperature specifications. These require design verification for voltage and temperature compatibility within the target application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required):

AM26LS32ACDR is the primary recommended substitute. It maintains identical electrical specifications, protocol support, supply voltage range, and operating temperature as the AM26LS32ACDE4. The part is in Active product status with significantly higher inventory availability (38,682 pcs) compared to the Last Time Buy main part. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect electrical performance or PCB integration.

AM26LS32ACD provides an alternative within the Texas Instruments AM26LS32 series with identical electrical parameters and Last Time Buy status. Inventory availability is higher (13,267 pcs) than the main part, though lower than AM26LS32ACDR.

For Cross-Manufacturer Substitution (Design Verification Required):

MAX3096ESE+T is recommended for applications requiring extended operating temperature range (-40°C to 85°C) and long-term availability. This part is in Active status with the highest inventory level (37,800 pcs). However, the supply voltage range (3V to 3.6V) differs from the main part and requires circuit design verification to confirm compatibility with existing power supply architecture.

MAX3096CSE+T offers similar extended availability and Active status with lower inventory (8,546 pcs). Operating temperature range matches the main part (0°C to 70°C), but supply voltage requirements remain different.

SP26LV432CN-L provides the highest data rate capability (50Mbps) and is suitable for high-speed serial communication applications. However, it is in Last Time Buy status and operates at a fixed 3.3V supply voltage, requiring design verification for voltage compatibility.

Frequently Asked Questions (FAQ)

Q: Can AM26LS32ACDR be used as a direct replacement for AM26LS32ACDE4?

A: Yes. AM26LS32ACDR is electrically and functionally identical to AM26LS32ACDE4. Both parts share the same receiver configuration (0/4), protocol support (RS422, RS423), supply voltage range (4.75V to 5.25V), operating temperature range (0°C to 70°C), and 16-SOIC package. The only difference is the packaging format (Cut Tape & Digi-Reel® versus Tube), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the key difference between the Texas Instruments AM26LS32 series and the Analog Devices MAX3096 series?

A: The primary difference is supply voltage range. The AM26LS32 series operates at 4.75V to 5.25V (5V logic), while the MAX3096 series operates at 3V to 3.6V (3.3V logic). Both provide equivalent receiver functionality and 16-SOIC packaging. Substitution between these families requires verification that the application power supply can accommodate the different voltage requirements.

Q: Is the SP26LV432CN-L compatible with 5V supply voltage applications?

A: No. The SP26LV432CN-L operates at a fixed 3.3V supply voltage and is not compatible with 5V supply voltage applications. This part is suitable only for 3.3V logic systems and requires design verification before substitution.

Q: What does "Last Time Buy" product status mean for component selection?

A: Last Time Buy status indicates that the manufacturer has announced end-of-life for the part and will no longer accept new orders after a specified date. Existing inventory may be available, but long-term supply cannot be guaranteed. For applications requiring sustained production, substitution to parts in Active status (such as AM26LS32ACDR or MAX3096ESE+T) is recommended.

Q: Can I substitute a MAX3096 part for an AM26LS32 part in an existing design without circuit modifications?

A: Not without verification. While both families provide equivalent receiver functionality and 16-SOIC packaging, the supply voltage ranges differ significantly (4.75V–5.25V versus 3V–3.6V). Circuit modifications to the power supply or voltage regulation may be required. Receiver hysteresis also differs slightly (50 mV versus 45 mV), which may affect signal integrity in marginal noise environments. Design verification is necessary before substitution.

Q: What is the significance of Moisture Sensitivity Level (MSL) rating?

A: MSL rating indicates the maximum time a component can be exposed to ambient moisture before soldering without baking. MSL 1 (Unlimited) means the part has no moisture sensitivity restrictions and can be stored indefinitely without special handling. MSL 2 (1 Year) requires that the part be soldered within one year of the manufacturing date or be baked before use. The AM26LS32ACDE4 and most substitutes carry MSL 1 rating, except SP26LV432CN-L which carries MSL 2.

Q: Are all listed substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this document are ROHS3 compliant, matching the compliance status of the AM26LS32ACDE4. This ensures compatibility with environmental regulations and procurement requirements for RoHS-compliant applications.
