Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD74HCT241M are classified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Critical Parameters for Substitution:

• Logic Type: Buffer, Non-Inverting
• Number of Elements: 2
• Number of Bits per Element: 4
• Output Type: 3-State
• Current - Output High, Low: 6mA, 6mA
• Voltage - Supply: 4.5V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Direct Substitute (Packaging Variant): CD74HCT241M96 is a direct substitute with identical electrical specifications and the same 20-SOIC package, differing only in packaging format (Cut Tape & Digi-Reel® versus Tube).

Parametric Equivalent (Base Product Variant): CD74HCT244M shares all critical electrical parameters and package specifications but uses a different base product number (74HCT244 versus 74HCT241), indicating a functionally equivalent device within the same logic family.

Manufacturer Alternatives: 74HCT241D,653 (NXP Semiconductors) and MC74HCT241ADWR2G (onsemi) meet all electrical and package requirements, with minor variations in operating temperature range and moisture sensitivity level.

Parametric Equivalent (Alternative Manufacturer): MC74HCT244ADWG (onsemi) provides parametric equivalence with the same electrical specifications and 20-SOIC package, using the 74HCT244 base product designation.

Parameter Comparison

Engineering Selection Recommendations

CD74HCT241M96 is the primary direct substitute, offering identical electrical specifications and 20-SOIC package configuration with active product status. This part maintains full compatibility with the original CD74HCT241M design while ensuring ongoing availability.

MC74HCT241ADWR2G (onsemi) provides an active alternative with equivalent electrical parameters and identical package specifications. The moisture sensitivity level is rated at MSL 3 (168 Hours) compared to MSL 1 (Unlimited) for the original part, requiring appropriate handling procedures during storage and assembly.

74HCT241D,653 (NXP Semiconductors) is an active substitute meeting all critical electrical parameters with a narrower operating temperature range of -40°C to 125°C (versus -55°C to 125°C for the original). This part is suitable for applications not requiring the extended low-temperature performance of the original specification.

CD74HCT244M and MC74HCT244ADWG are parametric equivalents using the 74HCT244 base product designation. These parts maintain all critical electrical specifications and package requirements, providing functional equivalence within the 74HCT logic family.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original CD74HCT241M specification.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT241M96 be used as a direct replacement for CD74HCT241M?

A: Yes. CD74HCT241M96 is a direct substitute with identical electrical specifications, logic configuration, and 20-SOIC package. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tube). Both parts are manufactured by Texas Instruments and meet the same performance requirements.

Q: What is the difference between CD74HCT244M and CD74HCT241M?

A: Both parts share identical electrical specifications, output current ratings, supply voltage range, operating temperature, and 20-SOIC package configuration. The difference lies in the base product number designation (74HCT244 versus 74HCT241), indicating a parametric equivalent within the same logic family.

Q: Can I use MC74HCT241ADWR2G if my application requires MSL 1 (Unlimited) moisture sensitivity?

A: MC74HCT241ADWR2G is rated MSL 3 (168 Hours), which is more restrictive than the original CD74HCT241M MSL 1 (Unlimited) rating. If your application requires unlimited moisture sensitivity, use CD74HCT241M96 or CD74HCT244M instead.

Q: Is 74HCT241D,653 suitable for applications requiring -55°C operation?

A: No. The 74HCT241D,653 operates from -40°C to 125°C, which does not meet the original -55°C to 125°C specification. Use this part only for applications with a minimum operating temperature of -40°C or higher.

Q: Are all substitute parts ROHS3 compliant?

A: CD74HCT241M96, CD74HCT244M, MC74HCT241ADWR2G, and MC74HCT244ADWG are all ROHS3 compliant. The 74HCT241D,653 RoHS status is not specified in the provided data.

Q: Can I interchange CD74HCT244M and MC74HCT244ADWG in the same circuit?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output current ratings, supply voltage, operating temperature range, and 20-SOIC package. The primary difference is manufacturer (Texas Instruments versus onsemi) and moisture sensitivity level (MSL 1 versus MSL 3).
