MM74HC241N Equivalent & Substitute Parts

Part Overview

The MM74HC241N is a non-inverting buffer logic integrated circuit manufactured by onsemi, designed for 2-element, 4-bit per element configurations with 3-state output capability. This device operates across a 2V to 6V supply voltage range and is housed in a 20-pin DIP package suitable for through-hole mounting applications.

The MM74HC241N is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for systems utilizing this logic buffer architecture.

Substitute Part Grouping Explanation

Substitute parts for the MM74HC241N are identified based on strict parametric equivalence across the following criteria:

• 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
• Operating Temperature: -55°C ~ 125°C (TA)
• Mounting Type: Through Hole
• Package / Case: 20-DIP (0.300", 7.62mm)
• Supplier Device Package: 20-PDIP

All identified substitute parts maintain identical electrical performance characteristics and mechanical compatibility with the original MM74HC241N specification.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CD74HC241E, CD74HC244E, and CD74HC244EE4—provide complete parametric equivalence to the MM74HC241N across all electrical and mechanical specifications.

For new designs or systems requiring regulatory compliance, CD74HC244E and CD74HC244EE4 are preferred selections, as both are ROHS3 compliant and maintain active product status with Texas Instruments. These parts ensure long-term availability and compliance with current environmental regulations.

CD74HC241E, manufactured by Harris Corporation, is also parametrically equivalent but carries obsolete product status and RoHS non-compliant classification, similar to the original MM74HC241N. This part is suitable for legacy system maintenance where compliance requirements are not applicable.

Frequently Asked Questions (FAQ)

Q: Can CD74HC244E or CD74HC244EE4 be used as direct replacements for MM74HC241N?

A: Yes. Both parts maintain identical electrical performance (2V to 6V supply, 7.8mA output current, -55°C to 125°C operating range) and mechanical compatibility (20-DIP package, through-hole mounting). No circuit modifications are required.

Q: What is the difference between CD74HC244E and CD74HC244EE4?

A: Both parts are manufactured by Texas Instruments and are parametrically identical. The primary distinction is packaging format (Tube for both), with CD74HC244EE4 designated as an alternative part number variant. Electrical and mechanical specifications are equivalent.

Q: Is CD74HC241E suitable for applications requiring RoHS compliance?

A: No. CD74HC241E carries RoHS non-compliant status. For applications requiring RoHS3 compliance, use CD74HC244E or CD74HC244EE4.

Q: Are there any pin configuration differences between these substitute parts?

A: No. All substitute parts utilize the 20-PDIP package configuration with identical pin assignments and mechanical dimensions (0.300", 7.62mm).

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

A: CD74HC244E and CD74HC244EE4, both manufactured by Texas Instruments with active product status, offer superior long-term availability compared to obsolete alternatives.
