Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26LS32ACPWE4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Receiver type and protocol support (RS422/RS423 capability)
• Number of drivers/receivers (0/4 configuration)
• Supply voltage range compatibility
• Operating temperature range
• Surface mount package compatibility
• RoHS3 compliance and MSL rating

Substitution Groups:

Group 1: Direct Texas Instruments Substitutes The AM26LS32ACPW maintains identical electrical specifications and protocol support as the AM26LS32ACPWE4, with the primary difference being packaging format (Tube vs. Tape/Reel). This part is obsolete but remains functionally equivalent.

Group 2: Analog Devices MAX3096 Series The MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, and MAX3096EEE+T are functionally compatible receivers with the following considerations:

• Support RS422 and RS485 protocols (RS422 overlap ensures compatibility)
• Identical 0/4 receiver configuration
• Lower supply voltage range (3V ~ 3.6V vs. 4.75V ~ 5.25V)
• Receiver hysteresis of 45 mV (vs. 50 mV)
• Data rate specification of 10Mbps
• Extended temperature variants available (-40°C ~ 85°C for EEE+ series)
• 16-QSOP package (0.154", 3.90mm Width) - physically compatible with 16-TSSOP footprint

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Specifications): Select AM26LS32ACPW when maintaining identical supply voltage (4.75V ~ 5.25V) and operating temperature (0°C ~ 70°C) requirements. This part is obsolete but maintains full functional equivalence. Packaging format differs (Tube vs. Tape/Reel) but does not affect electrical performance.

For Active Production (Recommended): The MAX3096 series (MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, MAX3096EEE+T) are active products with full availability. These parts are suitable for applications where:

• Supply voltage can be adjusted to 3V ~ 3.6V range
• RS422 protocol compatibility is required (RS485 support is additional)
• 10Mbps data rate meets application requirements

Temperature Considerations:

• Use MAX3096CEE+ or MAX3096CEE+T for standard industrial range (0°C ~ 70°C)
• Use MAX3096EEE+ or MAX3096EEE+T for extended temperature range (-40°C ~ 85°C)

Packaging and Availability: All substitute parts maintain surface mount technology. The MAX3096 series uses 16-QSOP packaging (0.154", 3.90mm Width) versus the original 16-TSSOP (0.173", 4.40mm Width). Both packages are compatible with standard 16-pin TSSOP/QSOP footprints. Packaging format (Tube, Cut Tape, or Digi-Reel) does not affect electrical performance.

Compliance: All listed parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory compatibility across substitution options.

Frequently Asked Questions (FAQ)

Q: Can the MAX3096 series directly replace the AM26LS32ACPWE4? A: Yes, functionally. The MAX3096 series supports RS422 protocol and maintains the 0/4 receiver configuration. Primary differences are supply voltage range (3V ~ 3.6V vs. 4.75V ~ 5.25V) and receiver hysteresis (45 mV vs. 50 mV). Circuit design must accommodate the lower supply voltage requirement.

Q: What is the difference between MAX3096CEE+ and MAX3096EEE+? A: The primary difference is operating temperature range. MAX3096CEE+ operates 0°C ~ 70°C, while MAX3096EEE+ operates -40°C ~ 85°C. Both maintain identical electrical specifications and protocol support. Select based on application temperature requirements.

Q: Does packaging format (Tube vs. Cut Tape) affect compatibility? A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical performance and pin configuration remain identical across all packaging options.

Q: Why is receiver hysteresis different between AM26LS32 and MAX3096 series? A: Hysteresis is an inherent design characteristic of each IC family. The 50 mV (AM26LS32) versus 45 mV (MAX3096) difference reflects different receiver threshold designs. Both values are within acceptable RS422 specifications for reliable signal reception.

Q: Can I use MAX3096 in a 5V supply circuit? A: No. The MAX3096 series is specified for 3V ~ 3.6V supply voltage. Operating outside this range violates manufacturer specifications and may cause device failure or unpredictable behavior.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed parts (AM26LS32ACPW, MAX3096CEE+, MAX3096CEE+T, MAX3096EEE+, MAX3096EEE+T) are ROHS3 compliant with MSL 1 rating, ensuring regulatory compliance for industrial and commercial applications.

Q: What is the difference between MAX3096CEE+T and MAX3096CEE+? A: The suffix "T" indicates Cut Tape (CT) & Digi-Reel packaging format, while the non-T variant uses Tube packaging. Electrical specifications and performance are identical; the difference is packaging and delivery format only.
