Key Parameters

Substitute Part Grouping Explanation

Substitution of the 74HC4024D,652 is determined by strict equivalence across the following parameters:

• Logic Type: Binary Counter
• Number of Elements: 1
• Number of Bits per Element: 7
• Direction: Up
• Reset: Asynchronous
• Trigger Type: Negative Edge
• Voltage - Supply: 2V ~ 6V
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in count rate and operating temperature ranges are noted but do not preclude functional substitution within the specified supply voltage and package constraints.

Parameter Comparison

Engineering Selection Recommendations

All three Texas Instruments CD74HC4024 variants (CD74HC4024M, CD74HC4024M96, CD74HC4024MT) are functionally equivalent to the 74HC4024D,652 across all critical electrical parameters and package specifications. Selection among these alternatives should be based on:

Product Status: CD74HC4024M96 maintains active product status, providing the most reliable long-term availability and supply chain continuity.

Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.

Packaging Format: CD74HC4024M96 (Tape & Reel) is optimized for high-volume automated assembly. CD74HC4024M (Tube) and CD74HC4024MT (Cut Tape & Digi-Reel®) accommodate lower-volume or mixed-format procurement scenarios.

Operating Temperature Range: Texas Instruments variants extend the lower operating temperature limit to -55°C, providing enhanced performance margin in cold environment applications compared to the original -40°C specification.

Frequently Asked Questions (FAQ)

Q: Can CD74HC4024M96 directly replace 74HC4024D,652 in existing designs?

A: Yes. Both parts share identical logic type, bit configuration, trigger mechanism, asynchronous reset, supply voltage range, and 14-SOIC package dimensions. The CD74HC4024M96 is a direct functional substitute.

Q: What is the significance of the different count rates (90 MHz vs. 35 MHz)?

A: The 74HC4024D,652 specifies a 90 MHz count rate, while Texas Instruments variants specify 35 MHz. Both rates exceed typical application requirements for 7-bit binary counters in standard logic circuits. The lower specification does not indicate reduced functionality but reflects different manufacturer characterization methodologies.

Q: Are there packaging considerations when switching from 74HC4024D,652 to CD74HC4024M96?

A: No. Both parts use identical 14-SOIC (0.154", 3.90mm Width) surface mount packages. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

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

A: CD74HC4024M96 is classified as active product status, indicating ongoing manufacturing and distribution support from Texas Instruments. This provides superior availability compared to discontinued alternatives.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All identified substitutes maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, matching the original part's regulatory profile.
