CD74HC4024MT Binary Counter 7-Bit Logic IC Equivalent & Substitute Parts

Part Overview

The CD74HC4024MT is a 7-bit binary counter logic integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This component functions as a negative edge-triggered counter with asynchronous reset capability, designed for digital counting and frequency division applications. The CD74HC4024MT is currently discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and production requirements. Equivalent parts maintain identical functional specifications and package compatibility while offering active product status and continued availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74HC4024MT is determined by strict equivalence across the following critical parameters:

• Logic Function: Binary counter with 7-bit capacity, up-counting direction, and negative edge trigger
• Electrical Specifications: Supply voltage range 2 V ~ 6 V, asynchronous reset, count rate minimum 35 MHz
• Package Compatibility: 14-SOIC surface mount package with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliance, MSL Level 1, REACH unaffected status
• Operating Range: Temperature range -55°C ~ 125°C or better

Substitute parts are grouped into two categories: parametric equivalents (identical specifications and packaging) and manufacturer-recommended alternatives (functionally equivalent with enhanced performance specifications).

Engineering Selection Recommendations

CD74HC4024M96 (Parametric Equivalent - Primary Substitute)

The CD74HC4024M96 is a direct parametric equivalent manufactured by Texas Instruments with active product status. This part maintains identical electrical specifications, operating temperature range, and package configuration as the CD74HC4024MT. The primary distinction is packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and current inventory availability (10,200 units in stock). This substitute is suitable for applications requiring exact specification matching and continued support from the original manufacturer.

74HC4024D,653 (Manufacturer-Recommended Alternative)

The 74HC4024D,653 manufactured by Nexperia USA Inc. is an active product with enhanced performance specifications. This part exceeds the minimum count rate requirement with 90 MHz capability versus the specified 35 MHz, providing performance margin for demanding applications. The operating temperature range is -40°C ~ 125°C, which covers the upper portion of the CD74HC4024MT specification. All other functional parameters, package dimensions, and compliance certifications remain equivalent. This substitute is appropriate for new designs or applications where enhanced speed performance is beneficial.

Both substitutes maintain ROHS3 compliance, MSL Level 1 rating, and identical pin configuration within the 14-SOIC package format, ensuring direct board-level compatibility.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4024M96 be used as a direct replacement for the CD74HC4024MT?

A: Yes. The CD74HC4024M96 is a parametric equivalent with identical electrical specifications, operating temperature range, and 14-SOIC package configuration. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel). Pin configuration and functional behavior are identical.

Q: What is the difference between the CD74HC4024M96 and the 74HC4024D,653?

A: Both are functionally equivalent substitutes. The CD74HC4024M96 is manufactured by Texas Instruments with identical specifications to the original part. The 74HC4024D,653 is manufactured by Nexperia USA Inc. and offers enhanced count rate performance (90 MHz versus 35 MHz) and a slightly narrower operating temperature range (-40°C to 125°C versus -55°C to 125°C). Both maintain identical package, pin configuration, and compliance certifications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 14-SOIC package with identical pin assignments. Direct board-level substitution is possible without circuit modification.

Q: Which substitute should be selected for new production designs?

A: Selection depends on application requirements. For designs requiring exact specification matching and original manufacturer continuity, use CD74HC4024M96. For applications benefiting from enhanced speed performance, use 74HC4024D,653. Both parts meet all compliance and environmental requirements.

Q: Do packaging format differences affect circuit performance?

A: No. Packaging format (Cut Tape & Digi-Reel versus Tape & Reel) affects only supply and handling logistics. Electrical performance and functional behavior are identical. The die and package case remain the same across all variants.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All three parts carry ROHS3 compliance certification and MSL Level 1 rating, meeting current environmental and regulatory requirements.
