74HCT241N,652 Equivalent & Substitute Parts

Part Overview

The 74HCT241N,652 is a non-inverting buffer logic integrated circuit manufactured by NXP Semiconductors. This device features 2 elements with 4 bits per element and 3-state output capability, housed in a 20-DIP package. The part operates across a 4.5V to 5.5V supply voltage range and supports operating temperatures from -40°C to 125°C. As an obsolete product status component, equivalent substitute parts are necessary for ongoing system maintenance, repair, and legacy design support where original inventory is depleted or unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 74HCT241N,652 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Core Electrical Parameters:

• 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

Mechanical Parameters:

• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

Series Compatibility:

• Base Product Number: 74HCT series

The identified substitute parts CD74HCT241E and CD74HCT244E maintain identical electrical specifications and package form factors, ensuring direct functional replacement in circuit applications. Both substitutes are manufactured by Harris Corporation and retain the same 74HCT logic family designation.

Parameter Comparison

Engineering Selection Recommendations

Both CD74HCT241E and CD74HCT244E provide functional equivalence to the 74HCT241N,652 across all critical electrical and mechanical parameters. The substitute parts maintain identical logic functionality, output drive capability, supply voltage range, and package form factor.

Compliance Considerations:

The original 74HCT241N,652 carries ROHS3 compliance certification. The Harris Corporation substitutes (CD74HCT241E and CD74HCT244E) are classified as RoHS non-compliant. For applications subject to RoHS regulatory requirements, this compliance difference must be evaluated against system-level requirements and procurement policies.

Operating Temperature Range:

The substitute parts support an extended lower operating temperature range (-55°C vs. -40°C minimum). This extended range provides additional margin for applications operating in cold environments and does not restrict use in standard temperature applications.

Availability and Inventory:

CD74HCT241E maintains 1309 units in stock, while CD74HCT244E maintains 1523 units in stock, compared to 938 units of the original part. Both substitutes are available in tube packaging.

Frequently Asked Questions (FAQ)

Q: Can CD74HCT241E and CD74HCT244E be used interchangeably with 74HCT241N,652?

A: Both substitute parts maintain identical electrical specifications (logic type, element count, bit configuration, output type, current ratings, and supply voltage). The 20-DIP through-hole package is mechanially identical. Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the difference between CD74HCT241E and CD74HCT244E?

A: Both parts share identical electrical parameters and package specifications. The primary distinction is the base product number designation (74HCT241 vs. 74HCT244), though both function as non-inverting buffers with 2 elements and 4 bits per element. Inventory availability differs, with CD74HCT244E offering 1523 units versus 1309 units for CD74HCT241E.

Q: Does the RoHS non-compliance of substitute parts affect functionality?

A: RoHS compliance is a regulatory and procurement classification, not a functional parameter. The RoHS non-compliant status of Harris substitutes does not impact electrical performance or circuit operation. Compliance requirements must be evaluated based on system-level regulatory obligations and customer specifications.

Q: Are the operating temperature ranges compatible?

A: The original part operates from -40°C to 125°C. Both substitutes operate from -55°C to 125°C. The extended lower temperature range of substitutes provides additional operational margin and does not restrict use in standard temperature applications.

Q: Is the 20-DIP package identical across all three parts?

A: Yes. All three parts use the 20-DIP (0.300", 7.62mm) through-hole package. Pin-to-pin compatibility and PCB footprint requirements are identical, enabling direct socket replacement without layout modifications.
