Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SN74ALS241CDW are identified based on strict parametric equivalence across the following critical criteria:

Electrical Parameters (Must Match):

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 15mA, 24mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: 0°C ~ 70°C (TA)

Mechanical Parameters (Must Match):

• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

Substitutes are grouped into two categories: MFR Recommended (same base product number with different packaging) and Parametric Equivalents (different base product numbers with identical electrical and mechanical specifications).

Parameter Comparison

Engineering Selection Recommendations

SN74ALS241CDWR (MFR Recommended Substitute): This part is the manufacturer-recommended equivalent to the SN74ALS241CDW, differing only in packaging format (Cut Tape versus Tube). The SN74ALS241CDWR maintains Active product status, providing superior long-term availability compared to the Last Time Buy status of the main part. All electrical, mechanical, and compliance parameters are identical. Selection of this part is appropriate for applications requiring extended procurement windows and ongoing supply chain stability.

SN74ALS244CDW and SN74ALS244C-1DW (Parametric Equivalents): These parts are parametric equivalents with identical electrical and mechanical specifications to the SN74ALS241CDW. Both parts are based on the 74ALS244 base product number rather than 74ALS241, but maintain full compatibility across all critical operating parameters. Both parts carry Last Time Buy status. These substitutes are suitable for direct replacement in circuit designs where the specific base product number is not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS241CDWR be used as a direct replacement for SN74ALS241CDW? A: Yes. The SN74ALS241CDWR is electrically and mechanically identical to the SN74ALS241CDW. The only difference is packaging format: SN74ALS241CDWR is supplied in Cut Tape (CT) while SN74ALS241CDW is supplied in Tube. Both are suitable for surface mount assembly. The SN74ALS241CDWR offers the advantage of Active product status.

Q: What is the difference between the MFR Recommended substitute and Parametric Equivalents? A: The MFR Recommended substitute (SN74ALS241CDWR) shares the same base product number (74ALS241) as the main part and differs only in packaging. Parametric Equivalents (SN74ALS244CDW and SN74ALS244C-1DW) have different base product numbers (74ALS244) but deliver identical electrical performance and mechanical compatibility. All three are valid substitutes based on functional parameters.

Q: Are all substitute parts RoHS3 compliant and REACH unaffected? A: Yes. All listed substitute parts maintain ROHS3 Compliant status and REACH Unaffected designation, matching the compliance profile of the main part SN74ALS241CDW.

Q: What is the Moisture Sensitivity Level (MSL) for these parts? A: All parts, including the main part and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the design does not impose constraints on base product number designation. All substitute parts deliver identical electrical performance (2-element, 4-bit buffer with 3-state output), operate within the same voltage and temperature ranges, and use the same 20-SOIC package. Mechanical and thermal characteristics are equivalent.
