MM74HC4060N Equivalent & Substitute Parts

Part Overview

The MM74HC4060N is a 14-bit binary counter logic IC manufactured by onsemi, housed in a 16-DIP package for through-hole mounting. This component functions as a single-element counter with asynchronous reset capability, operating at a maximum count rate of 30 MHz across a supply voltage range of 2V to 6V. The part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MM74HC4060N is determined by strict equivalence across the following critical parameters:

• Logic Type: Binary Counter
• Number of Bits per Element: 14 Bit
• Direction: Up
• Reset Type: Asynchronous
• Trigger Type: Negative Edge
• Package / Case: 16-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Base Product Number: 74HC4060

Both identified substitutes—CD74HC4060E (Harris Corporation) and SN74HC4060N (Texas Instruments)—meet these core functional and mechanical requirements. Variations in count rate, operating temperature range, and product status are secondary considerations that do not affect functional substitutability within the defined electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, the SN74HC4060N (Texas Instruments) is the preferred substitute. This part maintains active product status, ensuring long-term availability and manufacturer support. The SN74HC4060N is ROHS3 compliant, meeting current environmental and regulatory requirements for commercial and industrial applications.

The CD74HC4060E (Harris Corporation) remains functionally equivalent but carries obsolete status and RoHS non-compliance, limiting its suitability for new applications or regulated environments.

The MM74HC4060N and SN74HC4060N share identical operating temperature ranges (-40°C to 85°C), making them directly interchangeable in temperature-constrained applications. The CD74HC4060E offers an extended temperature range (-55°C to 125°C), which may be required for specialized industrial or military applications.

Frequently Asked Questions (FAQ)

Q: Can the CD74HC4060E replace the MM74HC4060N in existing designs?

A: Yes. Both parts share identical logic type, bit width, reset mechanism, trigger type, and 16-DIP package configuration. The CD74HC4060E's higher count rate (35 MHz vs. 30 MHz) and extended temperature range do not create incompatibility. However, RoHS non-compliance may restrict use in regulated applications.

Q: Is the SN74HC4060N a direct pin-for-pin replacement?

A: Yes. The SN74HC4060N is pin-for-pin compatible with the MM74HC4060N. Both use the 16-DIP package with identical pinout, supply voltage range (2V–6V), and asynchronous reset functionality.

Q: Why do the substitutes have different count rates?

A: Count rate variations (30 MHz, 33 MHz, 35 MHz) reflect manufacturing process differences between onsemi, Texas Instruments, and Harris Corporation. All rates exceed the minimum functional requirement for 74HC4060 operation. Selection should be based on application timing margins, not minimum count rate alone.

Q: Which substitute is suitable for RoHS-compliant applications?

A: The SN74HC4060N is ROHS3 compliant and is the appropriate choice for applications requiring environmental compliance certification. The CD74HC4060E is RoHS non-compliant and unsuitable for regulated procurement.

Q: Can I use the CD74HC4060E in high-temperature environments?

A: The CD74HC4060E operates across -55°C to 125°C, compared to -40°C to 85°C for both the MM74HC4060N and SN74HC4060N. If your application requires operation above 85°C, the CD74HC4060E is the only listed option. However, verify RoHS compliance requirements before selection.

Q: Are there packaging differences between these parts?

A: All three parts use identical 16-DIP (0.300", 7.62mm) through-hole packages. Packaging is not a differentiating factor for substitution. The CD74HC4060E is supplied in tube packaging, while specific packaging for MM74HC4060N and SN74HC4060N is not specified in the provided data.
