Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74ABT241CSJX is determined by the following critical parameters:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories:

Direct Substitutes (Pin-Compatible, Identical Base Product): Parts sharing the 74ABT241 base product number with matching electrical specifications and compatible packaging dimensions.

Parametric Equivalents (Functional Compatibility): Parts with identical electrical and thermal characteristics but different base product numbers or package dimensions, suitable for applications where pinout compatibility is not required.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement with Identical Output Current Specifications:

SN74ABT241ADW and SN74ABT241ADWR are the primary substitutes, maintaining the 74ABT241 base product number with matching 32mA/64mA output current ratings. Both are manufactured by Texas Instruments and carry Active product status with ROHS3 compliance. The primary difference is packaging format: SN74ABT241ADW is supplied in Tube packaging, while SN74ABT241ADWR is supplied in Tape & Reel format. Package dimensions differ from the original (0.295" vs 0.209" width), requiring PCB layout verification.

For Parametric Equivalence with Reduced Output Low Current:

SN74ABT2241DW and SN74ABT2241DWR provide functional equivalence with reduced output low current (12mA vs 64mA). These parts are suitable only for applications where the lower output current specification does not impact circuit performance. Both are Active status with ROHS3 compliance.

For Package Dimension Compatibility:

SN74ABT244ANSR maintains the original 0.209" package width dimension while providing identical electrical specifications (32mA/64mA output current). This part carries Active product status and ROHS3 compliance, making it suitable for designs requiring minimal PCB layout modification.

All substitute parts maintain the required 4.5V to 5.5V supply voltage range, -40°C to 85°C operating temperature, and MSL 1 rating. Selection should prioritize Active status parts (all Texas Instruments alternatives) over the obsolete original.

Frequently Asked Questions (FAQ)

Q: Can SN74ABT2241DW be used as a direct replacement for 74ABT241CSJX?

A: SN74ABT2241DW provides functional equivalence in logic operation but differs in output low current specification (12mA vs 64mA). Substitution is valid only if the application circuit can operate with reduced output current. Package dimensions also differ (0.295" vs 0.209" width), requiring PCB layout assessment.

Q: What is the primary difference between SN74ABT241ADW and SN74ABT241ADWR?

A: Both parts are electrically identical with matching 32mA/64mA output current specifications. The difference is packaging format: ADW is supplied in Tube, while ADWR is supplied in Tape & Reel. Selection depends on procurement and assembly requirements.

Q: Why does SN74ABT244ANSR have a different base product number?

A: SN74ABT244ANSR is classified as a parametric equivalent rather than a direct substitute. While it maintains identical electrical specifications and the original 0.209" package width, the different base product number (244 vs 241) indicates a distinct device variant. Functional compatibility is confirmed through matching logic type, element count, bit configuration, output type, and electrical ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All Texas Instruments substitute parts (SN74ABT241ADW, SN74ABT241ADWR, SN74ABT2241DW, SN74ABT2241DWR, and SN74ABT244ANSR) carry ROHS3 compliance certification. The original onsemi part does not specify RoHS status.

Q: What packaging considerations apply when substituting the 74ABT241CSJX?

A: The original part uses a 0.209" width 20-SOIC package. Most Texas Instruments substitutes use a 0.295" width 20-SOIC package, requiring PCB footprint verification. SN74ABT244ANSR maintains the 0.209" width, minimizing layout impact. Confirm PCB design compatibility before component selection.

Q: Which substitute offers the best long-term availability?

A: All Texas Instruments substitutes carry Active product status, indicating ongoing manufacturing and support. SN74ABT241ADW and SN74ABT241ADWR are recommended for designs requiring exact electrical specification matching (32mA/64mA output current) with established long-term availability.
