Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26LS32AIDRG4 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Package type: 16-SOIC surface mount form factor
• Receiver configuration: 0/4 (four receivers, no drivers)
• Protocol support: RS422 and/or RS423 compatibility
• Operating temperature range: Must support -40°C ~ 85°C minimum
• Supply voltage: Must operate within or encompass 4.75V ~ 5.25V range
• Receiver hysteresis: 45 mV to 60 mV acceptable tolerance
• RoHS3 compliance and MSL rating

Substitute Categories:

Direct Substitutes (Texas Instruments AM26LS32 Series): AM26LS32AIDR is the active production equivalent with identical electrical specifications and packaging, differing only in tape & reel format.

Cross-Manufacturer Substitutes (Analog Devices/Maxim MAX3096 Series): MAX3096CSE+, MAX3096CSE+T, MAX3096ESE+, and MAX3096ESE+T provide functional equivalence with RS422/RS485 protocol support. These parts operate at 3V ~ 3.6V supply voltage with 10Mbps data rate capability and 45 mV hysteresis. The extended temperature variants (ESE+T) support -40°C ~ 85°C operation, matching the original part's thermal range.

Alternative Substitute (MaxLinear SP26LV432CN-L): SP26LV432CN-L offers RS422/RS485 support with 3.3V supply, 50Mbps data rate, and 60 mV hysteresis. Operating temperature is limited to 0°C ~ 70°C, and product status is Last Time Buy.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: AM26LS32AIDR

The AM26LS32AIDR is the preferred substitute, offering identical electrical and thermal specifications to the AM26LS32AIDRG4. Both parts are Texas Instruments products with matching 4.75V ~ 5.25V supply voltage, -40°C ~ 85°C operating range, and 50 mV receiver hysteresis. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). This part maintains full compatibility with existing designs and has active product status with 8860 units in stock.

Secondary Recommendation: MAX3096ESE+T

For applications where supply voltage can be adjusted to 3V ~ 3.6V and full extended temperature operation (-40°C ~ 85°C) is required, the MAX3096ESE+T from Analog Devices/Maxim Integrated provides functional equivalence. This part supports RS422/RS485 protocols with 10Mbps data rate and 45 mV hysteresis. Highest inventory availability (37,800 units) ensures supply continuity. Design integration requires voltage regulation adjustment and circuit validation for the lower supply voltage range.

Tertiary Recommendation: MAX3096CSE+T

The MAX3096CSE+T offers the same electrical performance as MAX3096ESE+T but with restricted operating temperature range (0°C ~ 70°C). Selection is appropriate only for applications not requiring extended low-temperature operation below 0°C.

Not Recommended: SP26LV432CN-L

The SP26LV432CN-L has Last Time Buy status, indicating end-of-life production. Operating temperature range is limited to 0°C ~ 70°C, which does not meet the original part's -40°C ~ 85°C specification. This part should be avoided for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can I use MAX3096 series parts as direct drop-in replacements for AM26LS32AIDRG4?

A: Not without circuit modifications. The MAX3096 series operates at 3V ~ 3.6V supply voltage, while the AM26LS32AIDRG4 requires 4.75V ~ 5.25V. Power supply redesign is necessary. The 16-SOIC package pinout is identical, but voltage regulation must be implemented. The MAX3096ESE+T variant supports the full -40°C ~ 85°C temperature range of the original part.

Q: What is the difference between AM26LS32AIDR and AM26LS32AIDRG4?

A: Both parts are electrically identical with matching specifications. The difference is in packaging format: AM26LS32AIDRG4 is supplied in Tape & Reel (TR) format, while AM26LS32AIDR is supplied in Cut Tape (CT) & Digi-Reel format. Electrical performance, thermal range, and protocol support are identical.

Q: Why do the MAX3096 parts list RS485 support when the original part supports RS423?

A: RS485 is a superset protocol that encompasses RS423 functionality. The MAX3096 series supports both RS422 and RS485, providing broader protocol compatibility. For RS423-only applications, the MAX3096 parts operate in RS422 mode, which is compatible with RS423 receiver requirements.

Q: Is the 45 mV receiver hysteresis of MAX3096 parts acceptable compared to the 50 mV of AM26LS32AIDRG4?

A: Yes. Receiver hysteresis of 45 mV is within acceptable tolerance for RS422/RS423 applications. The lower hysteresis value provides improved noise immunity and faster signal transitions. This is a compatible parameter variation.

Q: Can I use SP26LV432CN-L in a design requiring -40°C operation?

A: No. The SP26LV432CN-L operating temperature range is 0°C ~ 70°C, which does not support operation below 0°C. For applications requiring -40°C minimum operation, use AM26LS32AIDR or MAX3096ESE+T variants.

Q: What inventory considerations should I evaluate?

A: AM26LS32AIDR has 8,860 units in stock with Active product status, ensuring long-term availability. MAX3096ESE+T has the highest inventory (37,800 units) and Active status. SP26LV432CN-L has Last Time Buy status with 2,833 units, indicating production discontinuation. For new designs, prioritize parts with Active status.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (AM26LS32AIDR, MAX3096 series, and SP26LV432CN-L) are ROHS3 compliant with MSL rating of 1 (Unlimited) or MSL 2 (1 Year), meeting environmental and regulatory requirements.
