Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HC241D,652 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
• Current - Output High, Low: 7.8mA, 7.8mA
• Voltage - Supply: 2V ~ 6V
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Substitute parts must maintain identical electrical specifications for logic function, output drive capability, and supply voltage range. Package compatibility requires the 20-SOIC form factor with matching 0.295" (7.50mm) width. Operating temperature range variations are acceptable provided the substitute covers the minimum required operating window.

Parameter Comparison

Engineering Selection Recommendations

CD74HC241M (Harris Corporation): This substitute maintains full electrical and mechanical compatibility with the 74HC241D,652. However, it carries RoHS non-compliance status, which may restrict use in applications subject to RoHS regulations. Product status is obsolete, limiting long-term availability.

CD74HC241M96 (Texas Instruments): This part provides complete functional equivalence with extended operating temperature range (-55°C to 125°C) and active product status, ensuring ongoing availability. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) support modern manufacturing and storage requirements. This is the preferred substitute for new designs and long-term procurement.

SN74HC241DW (Texas Instruments): Full electrical compatibility is maintained; however, the operating temperature range is limited to -40°C to 85°C, which is narrower than the original part. Product status is discontinued at DiGi Electronics, indicating reduced availability. ROHS3 compliance is present.

SN74HC241DWR (Texas Instruments): This part offers complete functional equivalence with active product status and ROHS3 compliance. Operating temperature range is -40°C to 85°C. Cut Tape and Digi-Reel packaging provides flexibility for both prototype and production quantities. This is a viable long-term substitute with strong availability.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC241M96 replace the 74HC241D,652 in all applications?

A: Yes, the CD74HC241M96 maintains identical electrical specifications for logic function, output drive current, and supply voltage range. The 20-SOIC package dimensions are identical. The extended operating temperature range (-55°C to 125°C) provides broader environmental coverage than the original part (-40°C to 125°C).

Q: What is the difference between SN74HC241DW and SN74HC241DWR?

A: Both parts are functionally identical with matching electrical specifications and package form factor. The primary difference is packaging format: SN74HC241DW is supplied in Tube packaging, while SN74HC241DWR is supplied in Cut Tape and Digi-Reel format. Selection depends on procurement quantity and handling requirements.

Q: Why is CD74HC241M not recommended despite full compatibility?

A: While CD74HC241M maintains complete electrical and mechanical compatibility, it carries RoHS non-compliance status. Additionally, both the original part and this substitute are classified as obsolete, which limits future availability and support. For new designs, active-status alternatives are preferred.

Q: Are there any temperature range limitations when substituting with SN74HC241DW or SN74HC241DWR?

A: Both Texas Instruments parts operate across -40°C to 85°C, which is narrower than the original 74HC241D,652 range of -40°C to 125°C. Applications requiring operation above 85°C must use CD74HC241M96, which supports temperatures up to 125°C.

Q: What packaging options are available for the substitute parts?

A: CD74HC241M is supplied in Tube packaging. CD74HC241M96 is supplied in Tape & Reel format. SN74HC241DW is supplied in Tube packaging. SN74HC241DWR is supplied in Cut Tape and Digi-Reel format. All maintain the identical 20-SOIC (0.295", 7.50mm Width) package form factor.

Q: Do all substitute parts meet RoHS3 compliance?

A: CD74HC241M does not meet RoHS compliance. CD74HC241M96, SN74HC241DW, and SN74HC241DWR all carry ROHS3 Compliant status, suitable for applications with RoHS regulatory requirements.
