CD74HC241M Equivalent & Substitute Parts

Part Overview

The CD74HC241M is a non-inverting buffer logic integrated circuit manufactured by Texas Instruments, designed for 2V to 6V supply voltage operation. This device functions as a 2-element, 4-bit per element buffer with 3-state output capability in a 20-SOIC surface mount package. The CD74HC241M is classified as Last Time Buy, indicating limited availability and the necessity to identify equivalent or substitute components for ongoing design requirements and production planning.

Substitute Part Grouping Explanation

Substitution of the CD74HC241M is determined by strict equivalence across 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
• Operating Temperature Range: -55°C ~ 125°C (TA)
• Package / Case: 20-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

Substitute parts are grouped into two categories: MFR Recommended substitutes (same base product number and packaging format) and Parametric Equivalents (identical electrical specifications with alternative base product numbers or packaging).

Parameter Comparison

Engineering Selection Recommendations

CD74HC241M96 (Texas Instruments, Active Status): This is the primary MFR recommended substitute. It maintains identical electrical specifications and package geometry to the CD74HC241M while offering Active product status and higher inventory availability (3135 Pcs). The only difference is packaging format (Tape & Reel vs. Tube), which does not affect electrical performance or board-level compatibility.

74HC241D,653 (NXP Semiconductors, Active Status): This part provides full parametric equivalence with ROHS3 compliance and substantial inventory (27298 Pcs). The operating temperature range is narrower (-40°C to 125°C vs. -55°C to 125°C), which may be acceptable for applications not requiring extended low-temperature operation. Packaging format is Bulk, suitable for high-volume production environments.

CD74HC244M (Texas Instruments, Discontinued at DiGi Electronics): While electrically equivalent, this part is listed as discontinued and should not be selected for new designs or long-term production planning.

MC74HC244ADWG (onsemi, Active Status): This parametric equivalent maintains all critical electrical specifications and ROHS3 compliance. The Moisture Sensitivity Level is MSL 3 (168 Hours) compared to MSL 1 for other options, which may require additional handling precautions in humid environments. Inventory availability is 2000 Pcs.

Frequently Asked Questions (FAQ)

Q: Can CD74HC241M96 be used as a direct replacement for CD74HC241M?

A: Yes. CD74HC241M96 is electrically and mechanically identical to CD74HC241M. The only difference is packaging format (Tape & Reel vs. Tube), which does not affect circuit performance or PCB assembly compatibility.

Q: What is the difference between the 74HC241 and 74HC244 base product numbers?

A: Both are non-inverting buffers with identical electrical specifications (2 elements, 4 bits per element, 3-state output, 7.8mA output current). The difference lies in internal logic configuration and pin arrangement. Substitution between these base numbers requires verification of pin compatibility with the target circuit design.

Q: Is the NXP 74HC241D,653 suitable for applications requiring -55°C operation?

A: No. The NXP part specifies an operating temperature range of -40°C to 125°C (TA), which does not cover the full -55°C to 125°C range of the CD74HC241M. Selection of this part should be limited to applications with minimum operating temperature of -40°C or higher.

Q: What does MSL 3 (168 Hours) mean for the MC74HC244ADWG?

A: Moisture Sensitivity Level 3 indicates the component can be exposed to ambient conditions (up to 85% relative humidity and 30°C) for a maximum of 168 hours before soldering. Components with MSL 1 (Unlimited) have no such time restriction. For applications with extended storage or exposure to humid environments, MSL 1 parts are preferred.

Q: Are all substitute parts ROHS3 compliant?

A: The CD74HC241M96, CD74HC244M, and MC74HC244ADWG are confirmed ROHS3 compliant. The NXP 74HC241D,653 does not specify RoHS status in the provided data. Verification with the manufacturer is recommended if RoHS compliance is a design requirement.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical substitution is possible for all listed parts with the exception of the temperature range limitation on the NXP part and the MSL 3 handling requirement for the onsemi part. However, pin-level compatibility must be verified, particularly when substituting between different base product numbers (74HC241 vs. 74HC244). PCB layout and schematic review is required before implementation.
