AM26LS32AIDR Equivalent & Substitute Parts

Part Overview

The AM26LS32AIDR is a 0/4 Receiver IC for RS422 and RS423 serial communication protocols, manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are necessary when the primary part experiences supply constraints, when alternative packaging formats are required, or when design specifications permit operation within the electrical and mechanical tolerances of equivalent receiver ICs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AM26LS32AIDR is determined by the following critical parameters:

Mechanical Compatibility: All substitute parts must use the 16-SOIC (0.154", 3.90mm Width) package to ensure PCB footprint compatibility without redesign.

Functional Equivalence: Substitute parts must support 0/4 receiver configuration and operate as serial communication interface receivers.

Protocol Support: The AM26LS32AIDR supports RS422 and RS423 protocols. Substitute parts must support RS422 as a minimum requirement; RS485 support is acceptable as RS485 is electrically compatible with RS422 receiver operation.

Electrical Parameters: Receiver hysteresis, supply voltage range, and operating temperature range determine functional substitutability. Parts with overlapping or extended operating ranges and compatible hysteresis specifications are qualified substitutes.

Compliance & Status: All substitute parts must maintain RoHS3 compliance and active or equivalent product status to ensure long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

MAX3096ESE+T (Preferred Substitute): This part offers the closest operational alignment with the AM26LS32AIDR. It maintains the extended operating temperature range of -40°C to 85°C, matching the original specification. Active product status ensures continued availability. The 16-SOIC package is mechanically identical. Cut Tape packaging format provides 37,800 units in stock, supporting high-volume applications. RoHS3 compliance and MSL 1 rating match the original part's environmental specifications.

MAX3096ESE+ (Alternative Substitute): Functionally equivalent to MAX3096ESE+T with identical electrical specifications and extended temperature range. Tube packaging format is available with 2,100 units in stock. Selection depends on packaging format requirements and supply chain preferences.

MAX3096CSE+T (Limited Temperature Range Substitute): Suitable for applications with operating temperature constraints between 0°C and 70°C. Cut Tape packaging with 8,546 units in stock. Active product status maintained. Use only when thermal environment permits reduced operating range.

MAX3096CSE+ (Limited Temperature Range Substitute): Functionally equivalent to MAX3096CSE+T with identical electrical specifications. Tube packaging with 2,000 units in stock. Selection depends on packaging format and temperature operating range compatibility.

SP26LV432CN-L (Last Time Buy Status): This part is classified as Last Time Buy, indicating discontinued production with limited remaining inventory (2,833 units). Operating temperature range restricted to 0°C to 70°C. Moisture sensitivity level MSL 2 requires controlled storage conditions. Use only when supply of active alternatives is unavailable and application thermal requirements permit reduced operating range. Not recommended for new designs.

Frequently Asked Questions (FAQ)

Q: Can MAX3096 series parts directly replace the AM26LS32AIDR without PCB modifications?

A: Yes. All MAX3096 variants use the identical 16-SOIC (0.154", 3.90mm Width) package, ensuring direct footprint compatibility. No PCB layout changes are required.

Q: What is the primary electrical difference between the AM26LS32AIDR and MAX3096 substitutes?

A: The AM26LS32AIDR operates at 4.75V to 5.25V supply voltage, while MAX3096 parts operate at 3V to 3.6V (or 3.3V for SP26LV432CN-L). Designs must verify power supply compatibility before substitution. The receiver hysteresis differs slightly: 50 mV for AM26LS32AIDR versus 45 mV for MAX3096 parts and 60 mV for SP26LV432CN-L.

Q: Are RS485-capable substitutes compatible with RS422-only designs?

A: Yes. RS485 receivers are electrically compatible with RS422 signal levels and protocols. All MAX3096 and SP26LV432CN-L parts support both RS422 and RS485, making them suitable for RS422 applications.

Q: Which substitute part has the best long-term availability?

A: MAX3096ESE+T is recommended for long-term availability. It maintains Active product status with the highest inventory level (37,800 units) and extended operating temperature range matching the original part.

Q: What is the significance of the "Last Time Buy" status for SP26LV432CN-L?

A: Last Time Buy indicates the manufacturer has discontinued production. Remaining inventory is limited (2,833 units). This part should not be selected for new designs. Use only when alternative substitutes are unavailable and application requirements permit its reduced operating temperature range and MSL 2 moisture sensitivity.

Q: Does packaging format (Cut Tape vs. Tube) affect electrical performance?

A: No. Packaging format affects only handling, storage, and supply chain logistics. Electrical and functional performance is identical between Cut Tape (CT) and Tube packaging variants of the same part number.

Q: Can the AM26LS32AIDR be used in applications designed for 3.3V supply voltage?

A: No. The AM26LS32AIDR requires 4.75V to 5.25V supply voltage and is not rated for 3.3V operation. For 3.3V applications, use MAX3096 series parts or SP26LV432CN-L, which are specified for lower voltage operation.

Q: What is the operating temperature range consideration for substitute selection?

A: The AM26LS32AIDR operates from -40°C to 85°C. MAX3096ESE+ and MAX3096ESE+T maintain this range. MAX3096CSE+, MAX3096CSE+T, and SP26LV432CN-L are limited to 0°C to 70°C. Select substitutes based on application thermal environment requirements.
