CD74HC4024M 7-Bit Binary Counter Equivalent & Substitute Parts

Part Overview

The CD74HC4024M is a 7-bit binary counter IC manufactured by Texas Instruments in a 14-SOIC surface mount package. This component functions as a negative edge-triggered counter with asynchronous reset capability, operating across a 2V to 6V supply voltage range. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain identical logic functionality, package compatibility, and electrical performance within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the CD74HC4024M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Logic Type: Binary Counter
• Number of Bits: 7 Bit
• Direction: Up
• Number of Elements: 1
• Reset Type: Asynchronous
• Trigger Type: Negative Edge
• Package Type: 14-SOIC
• Voltage Supply Range: 2V to 6V
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Count Rate: Substitute parts may exceed the 35 MHz specification
• Operating Temperature: Substitute parts may have narrower temperature ranges
• Packaging Format: Tube, Tape & Reel, or other standard formats are interchangeable for the same package type
• Manufacturer: Different manufacturers within the 74HC4024 series maintain functional equivalence

The identified substitutes CD74HC4024M96 (Texas Instruments, Tape & Reel) and 74HC4024D,653 (Nexperia USA Inc., Tape & Reel) meet all mandatory matching parameters and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both identified substitutes are functionally equivalent to the CD74HC4024M and are suitable for direct replacement in applications requiring a 7-bit binary counter with negative edge triggering and asynchronous reset.

CD74HC4024M96 (Texas Instruments, Tape & Reel): This substitute maintains identical electrical specifications to the main part, including the 35 MHz count rate and full -55°C to 125°C operating temperature range. Product status is Active, ensuring continued availability. Selection of this part preserves design margins and maintains consistency with the original Texas Instruments manufacturer lineage.

74HC4024D,653 (Nexperia USA Inc., Tape & Reel): This substitute provides enhanced count rate performance at 90 MHz, exceeding the original 35 MHz specification. Operating temperature range is -40°C to 125°C, which is narrower than the main part but remains suitable for most industrial and commercial applications. Product status is Active with established supply availability. This part is manufacturer-recommended and represents an alternative source within the 74HC4024 series.

Both substitutes are ROHS3 compliant with MSL rating 1 (Unlimited) and maintain the required 14-SOIC package footprint for direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4024M96 be used as a direct replacement for CD74HC4024M?

A: Yes. CD74HC4024M96 is a direct functional equivalent. Both parts are manufactured by Texas Instruments, share identical logic specifications, and operate across the same voltage and temperature ranges. The primary difference is packaging format: CD74HC4024M is supplied in Tube format while CD74HC4024M96 is supplied in Tape & Reel format. Both formats contain the same die and are electrically interchangeable.

Q: What is the difference between the Texas Instruments and Nexperia substitutes?

A: Both parts are functionally equivalent 7-bit binary counters within the 74HC4024 series. The Nexperia part (74HC4024D,653) offers a higher count rate specification of 90 MHz compared to 35 MHz, providing additional performance margin. The Nexperia part has a narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). Selection depends on application temperature requirements and supply chain availability.

Q: Are package dimensions identical across all three parts?

A: Yes. All three parts use the 14-SOIC package with dimensions of 0.154" width and 3.90mm width. PCB footprints are identical, and parts are mechanically interchangeable on the same circuit board layout.

Q: Why is the CD74HC4024M discontinued?

A: The CD74HC4024M is listed as discontinued at DiGi Electronics. Active substitutes CD74HC4024M96 and 74HC4024D,653 remain in production and are recommended for new designs and ongoing production requirements.

Q: Do all substitutes meet RoHS and REACH compliance?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the significance of MSL rating 1 (Unlimited)?

A: MSL rating 1 (Unlimited) indicates the lowest moisture sensitivity level. These parts have no moisture-related storage or handling restrictions and do not require special dry-pack storage or baking procedures prior to soldering.
