AM26LS33ACDG4 Equivalent & Substitute Parts

Part Overview

The AM26LS33ACDG4 is a 0/4 Receiver interface IC manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating limited future availability. The part operates within a 4.75V to 5.25V supply voltage range and supports operating temperatures from 0°C to 70°C. Finding equivalent and substitute parts is necessary due to the Last Time Buy status and to ensure design flexibility for procurement and long-term supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the AM26LS33ACDG4 is determined by the following critical parameters:

Primary Substitution Criteria:

• Number of Drivers/Receivers: 0/4 configuration
• Package Type: 16-SOIC surface mount form factor
• Receiver Hysteresis: 50 mV or compatible tolerance
• Supply Voltage Range: Compatibility with 4.75V to 5.25V operation
• RoHS3 Compliance and MSL rating

Substitution Groups:

Group 1 - Direct Texas Instruments Equivalents (Same Base Series): AM26LS33ACD and AM26LS33ACDR are direct variants of the AM26LS33 base product. These parts maintain identical electrical specifications, receiver hysteresis, and voltage supply parameters. The primary difference is packaging format (Tube vs. Cut Tape/Digi-Reel).

Group 2 - Extended Temperature Range Alternatives (DS26C32 Series): DS26C32ATM/NOPB and DS26C32ATMX/NOPB are Texas Instruments parts with expanded operating temperature range (-40°C to 85°C) and slightly higher receiver hysteresis (60 mV). These support RS422 and RS423 protocols. Supply voltage range is 4.5V to 5.5V, which encompasses the AM26LS33ACDG4 operating window.

Group 3 - Alternative Manufacturer Option (MaxLinear): SP26LV432CN-L is a MaxLinear receiver with 0/4 configuration and 16-SOIC packaging. This part operates at 3.3V supply voltage with 50 Mbps data rate capability and supports RS422/RS485 protocols. Operating temperature range is 0°C to 70°C, matching the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications): AM26LS33ACDR is the preferred substitute. It maintains all electrical parameters of the AM26LS33ACDG4 while offering Active product status and higher inventory availability (10,200 pcs). The Cut Tape and Digi-Reel packaging format provides flexibility for both prototype and production quantities.

For Extended Operating Temperature Requirements: DS26C32ATMX/NOPB is suitable when designs require operation beyond 0°C to 70°C range. This part extends to -40°C to 85°C and maintains ROHS3 compliance. The expanded supply voltage range (4.5V to 5.5V) provides additional design margin. Active product status and highest inventory (22,854 pcs) ensure long-term availability.

For Alternative Manufacturer Sourcing: SP26LV432CN-L from MaxLinear provides a 0/4 receiver in 16-SOIC packaging with identical operating temperature range. This option is applicable only for designs operating at 3.3V supply voltage. Last Time Buy status limits future procurement options.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and EAR99 classification. MSL ratings are acceptable for standard surface mount assembly processes. Parts with Active status (AM26LS33ACDR, DS26C32ATM/NOPB, DS26C32ATMX/NOPB) are recommended for new designs requiring long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can AM26LS33ACD replace AM26LS33ACDG4 directly? A: Yes. Both parts share identical electrical specifications, receiver hysteresis (50 mV), supply voltage range (4.75V to 5.25V), and operating temperature (0°C to 70°C). The difference is packaging format (Tube). Both are Last Time Buy status.

Q: What is the difference between AM26LS33ACDR and AM26LS33ACD? A: Electrical specifications are identical. AM26LS33ACDR uses Cut Tape and Digi-Reel packaging, while AM26LS33ACD uses Tube packaging. AM26LS33ACDR has Active product status with significantly higher inventory (10,200 pcs vs. 3,300 pcs).

Q: Can DS26C32ATM/NOPB be used in place of AM26LS33ACDG4? A: Functional substitution is possible. Both are 0/4 receivers in 16-SOIC packages with ROHS3 compliance. DS26C32ATM/NOPB has higher receiver hysteresis (60 mV vs. 50 mV) and expanded operating temperature (-40°C to 85°C). Supply voltage range is broader (4.5V to 5.5V), which is compatible with the AM26LS33ACDG4 operating window.

Q: Is SP26LV432CN-L compatible with AM26LS33ACDG4? A: Compatibility depends on system supply voltage. SP26LV432CN-L operates at 3.3V, while AM26LS33ACDG4 requires 4.75V to 5.25V. If your design uses 3.3V supply, SP26LV432CN-L is functionally equivalent as a 0/4 receiver in 16-SOIC packaging. MSL rating is 2 (1 Year) instead of 1 (Unlimited).

Q: Which substitute has the best long-term availability? A: DS26C32ATMX/NOPB has the highest inventory (22,854 pcs) and Active product status, ensuring continued manufacturing and supply. AM26LS33ACDR is the second choice with 10,200 pcs and Active status.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and are suitable for applications requiring environmental compliance certification.

Q: What packaging formats are available for substitutes? A: AM26LS33ACD and DS26C32ATM/NOPB are supplied in Tube format. AM26LS33ACDR and DS26C32ATMX/NOPB are supplied in Cut Tape and Digi-Reel format. SP26LV432CN-L is supplied in Tube format. Select based on procurement volume and assembly requirements.
