CD4024BM Binary Counter 7-Bit Logic IC Equivalent & Substitute Parts

Part Overview

The CD4024BM is a 7-bit binary counter logic IC manufactured by Texas Instruments in the 4000B series. This component functions as a negative edge-triggered counter with asynchronous reset capability, designed for digital counting and frequency division applications. The CD4024BM is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain identical functional specifications, package configuration, and electrical performance parameters to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CD4024BM is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Logic Type: Binary Counter
• Number of Bits per Element: 7 Bit
• Number of Elements: 1
• Direction: Up
• Trigger Type: Negative Edge
• Reset: Asynchronous
• Package / Case: 14-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Voltage - Supply: 3 V ~ 18 V
• Operating Temperature: -55°C ~ 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Performance Consideration: Count Rate specifications may vary between manufacturers while maintaining functional compatibility. The CD4024BM operates at 24 MHz, while certain substitute parts operate at 12 MHz. Selection depends on application frequency requirements.

All identified substitute parts meet the mandatory parameter requirements and are qualified for direct replacement in applications where the specified electrical and thermal characteristics are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute - CD4024BM96 (Texas Instruments): CD4024BM96 is the direct equivalent from the original manufacturer with identical 24 MHz count rate specification. This part maintains full functional parity with the discontinued CD4024BM and is available in active production status with highest inventory availability (22055 units). Recommended for applications requiring maximum performance consistency and manufacturer continuity.

Alternative Substitutes - onsemi Parts (MC14024BDG, MC14024BDR2G, NLV14024BDR2G): All onsemi-manufactured parts (MC14024BDG, MC14024BDR2G, NLV14024BDR2G) are functionally qualified substitutes meeting all mandatory electrical and mechanical parameters. These parts operate at 12 MHz count rate, which is half the CD4024BM specification. Selection of onsemi parts is appropriate for applications where the 12 MHz count rate satisfies system frequency requirements. All onsemi substitutes maintain ROHS3 compliance, identical supply voltage range (3 V ~ 18 V), and operating temperature specifications (-55°C ~ 125°C).

Packaging Considerations:

• CD4024BM96 available in Cut Tape & Digi-Reel format for automated assembly
• MC14024BDG available in Tube packaging
• MC14024BDR2G and NLV14024BDR2G available in Tape & Reel format for high-volume production

All substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CD4024BM96 be used as a direct replacement for CD4024BM? A: Yes. CD4024BM96 is manufactured by Texas Instruments and maintains identical specifications including 24 MHz count rate, 7-bit binary counter function, negative edge trigger, asynchronous reset, 14-SOIC package, and operating temperature range (-55°C ~ 125°C). The primary difference is packaging format (Cut Tape & Digi-Reel vs. Tube).

Q: What is the difference between CD4024BM and onsemi substitutes? A: The primary difference is count rate: CD4024BM and CD4024BM96 operate at 24 MHz, while MC14024BDG, MC14024BDR2G, and NLV14024BDR2G operate at 12 MHz. All other functional parameters (7-bit binary counter, negative edge trigger, asynchronous reset, supply voltage 3 V ~ 18 V, operating temperature -55°C ~ 125°C) are identical. Selection depends on application frequency requirements.

Q: Are all substitute parts ROHS3 compliant? A: Yes. CD4024BM96, MC14024BDG, MC14024BDR2G, and NLV14024BDR2G are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What packaging formats are available for substitutes? A: CD4024BM96 is available in Cut Tape & Digi-Reel format. MC14024BDG is available in Tube. MC14024BDR2G and NLV14024BDR2G are available in Tape & Reel format. Selection should align with assembly process requirements.

Q: Can MC14024BDG be used in place of CD4024BM in high-frequency applications? A: MC14024BDG operates at 12 MHz maximum count rate, compared to CD4024BM's 24 MHz specification. Use MC14024BDG only in applications where 12 MHz count rate is acceptable for system performance.

Q: What is the difference between MC14024BDR2G and NLV14024BDR2G? A: Both parts are manufactured by onsemi with identical electrical specifications (12 MHz count rate, 7-bit binary counter, negative edge trigger, asynchronous reset, 14-SOIC package). Both are available in Tape & Reel packaging. The primary difference is the part number prefix (MC vs. NLV), which may indicate different manufacturing lines or product variants. Consult onsemi documentation for specific variant details.
