Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM26LS32AIDG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Type: Receiver
• Number of Drivers/Receivers: 0/4
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Secondary Compatibility Criteria:

• Protocol Support: RS422 and/or RS423
• Operating Temperature Range: Must encompass or match -40°C ~ 85°C
• Voltage - Supply: Must be compatible with 4.75V ~ 5.25V or provide overlapping range
• Receiver Hysteresis: 45 mV to 60 mV acceptable range

All identified substitute parts maintain identical package specifications and mounting characteristics, ensuring direct PCB compatibility. Protocol support varies among substitutes, with some offering extended RS485 capability in addition to RS422/RS423 support.

Parameter Comparison

Engineering Selection Recommendations

Texas Instruments AM26LS32 Series (AM26LS32AID, AM26LS32AIDR): These parts provide direct electrical and functional equivalence to the AM26LS32AIDG4. Both maintain identical receiver hysteresis (50 mV), supply voltage range (4.75V ~ 5.25V), and operating temperature range (-40°C ~ 85°C). AM26LS32AIDR is recommended for new designs due to Active product status and availability in Cut Tape & Digi-Reel® packaging, offering superior supply chain continuity compared to the Last Time Buy AM26LS32AID.

Analog Devices Inc./Maxim Integrated MAX3096 Series (MAX3096ESE+T, MAX3096ESE+): These parts offer extended operating temperature range (-40°C ~ 85°C) matching the original specification. MAX3096ESE+T is preferred for production due to Active status and Cut Tape & Digi-Reel® packaging availability. These parts support RS422 and RS485 protocols with 10Mbps data rate capability. Supply voltage operates at 3V ~ 3.6V, requiring voltage regulation or power supply modification in systems designed for 5V operation.

MaxLinear SP26LV432CN-L: This part operates at 3.3V with 50Mbps data rate capability and 60 mV receiver hysteresis. Operating temperature range is limited to 0°C ~ 70°C, making it unsuitable for applications requiring -40°C operation. Product status is Last Time Buy, limiting long-term availability.

Recommendation Priority:

1. AM26LS32AIDR (Texas Instruments) — Direct equivalent, Active status, optimal supply chain position
2. MAX3096ESE+T (Analog Devices Inc./Maxim Integrated) — Active status, extended temperature range, requires power supply consideration
3. MAX3096ESE+ (Analog Devices Inc./Maxim Integrated) — Active status, Tube packaging alternative

Frequently Asked Questions (FAQ)

Q: Can AM26LS32AIDR be used as a direct replacement for AM26LS32AIDG4? A: Yes. Both parts share identical electrical specifications including receiver hysteresis (50 mV), supply voltage range (4.75V ~ 5.25V), operating temperature range (-40°C ~ 85°C), and 16-SOIC package. The primary difference is packaging format (Tube vs. Cut Tape & Digi-Reel®) and product status (Last Time Buy vs. Active).

Q: What are the limitations of MAX3096 series substitutes? A: MAX3096 parts operate at 3V ~ 3.6V supply voltage, requiring voltage regulation if the system is designed for 5V operation. Operating temperature range for MAX3096CSE+ and MAX3096CSE+T is limited to 0°C ~ 70°C, unsuitable for extended temperature applications. MAX3096ESE+ and MAX3096ESE+T support the full -40°C ~ 85°C range.

Q: Is SP26LV432CN-L suitable for all applications? A: SP26LV432CN-L is not recommended for applications requiring -40°C operation, as its minimum operating temperature is 0°C. Additionally, Last Time Buy status indicates limited future availability.

Q: What is the significance of receiver hysteresis differences? A: Receiver hysteresis values (45 mV to 60 mV) fall within acceptable tolerance for RS422/RS423/RS485 interface standards. Hysteresis differences do not prevent functional substitution but may affect noise immunity characteristics in specific applications.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All identified substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, meeting environmental and regulatory requirements equivalent to the original AM26LS32AIDG4.

Q: What packaging options are available for production? A: Texas Instruments AM26LS32AIDR is available in Cut Tape (CT) & Digi-Reel® packaging. Analog Devices MAX3096ESE+T and MAX3096CSE+T offer Cut Tape & Digi-Reel® options. Tube packaging is available for AM26LS32AID, MAX3096ESE+, MAX3096CSE+, and SP26LV432CN-L.
