Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74HCT4060N,652 is determined by strict alignment of the following critical parameters:

• Logic Type: Binary Counter (1 Element, 14 Bit)
• Direction: Up
• Reset: Asynchronous
• Trigger Type: Negative Edge
• Package / Case: 16-DIP (0.300", 7.62mm)
• Voltage - Supply: 4.5 V ~ 5.5 V
• Mounting Type: Through Hole

The CD74HCT4060E qualifies as a direct substitute based on matching all functional and mechanical parameters. Both devices share the same base product number (74HCT4060), identical pin configuration, and compatible electrical specifications within the defined supply voltage range.

Parameter Comparison

Engineering Selection Recommendations

The CD74HCT4060E serves as a functional equivalent to the 74HCT4060N,652 for applications where the primary requirement is binary counting with asynchronous reset and negative edge triggering in a 16-DIP package. Both devices operate within identical supply voltage specifications and share compatible pin assignments.

Selection between these parts should account for the following considerations:

The 74HCT4060N,652 maintains ROHS3 compliance, making it suitable for applications subject to environmental or regulatory restrictions on hazardous substances. The CD74HCT4060E, while non-compliant with RoHS standards, offers an extended lower operating temperature limit (-55°C versus -40°C), providing broader thermal range coverage for specialized applications.

The count rate differential (88 MHz versus 30 MHz) reflects manufacturing variations between NXP and Harris implementations of the 74HCT4060 architecture. Applications operating at frequencies below 30 MHz experience no functional limitation with the CD74HCT4060E. Systems requiring operation at frequencies between 30 MHz and 88 MHz must use the 74HCT4060N,652 or identify alternative counter architectures.

Frequently Asked Questions (FAQ)

Q: Can the CD74HCT4060E replace the 74HCT4060N,652 in all applications?

A: The CD74HCT4060E is functionally compatible for applications operating at count rates up to 30 MHz. Applications requiring count rates between 30 MHz and 88 MHz require the 74HCT4060N,652 or an alternative counter IC. Both devices share identical pin configuration and package dimensions, enabling direct socket substitution where frequency requirements are met.

Q: What is the significance of the RoHS compliance difference?

A: The 74HCT4060N,652 is ROHS3 compliant, indicating compliance with Restriction of Hazardous Substances regulations. The CD74HCT4060E is RoHS non-compliant. Selection depends on regulatory requirements applicable to the end application and geographic market.

Q: Are the operating temperature ranges interchangeable?

A: The CD74HCT4060E supports operation from -55°C to 125°C, while the 74HCT4060N,652 operates from -40°C to 125°C. The CD74HCT4060E accommodates extended low-temperature operation. For applications within the -40°C to 125°C range, both devices are equivalent. Applications requiring operation below -40°C must use the CD74HCT4060E.

Q: Do both parts use the same 16-DIP package?

A: Yes. Both the 74HCT4060N,652 and CD74HCT4060E use the 16-DIP (0.300", 7.62mm) through-hole package with identical pin assignments, enabling direct mechanical and electrical substitution within the specified parameter constraints.

Q: What supply voltage range applies to both devices?

A: Both devices operate across 4.5 V to 5.5 V supply voltage range, ensuring compatibility in systems designed for standard TTL-compatible logic levels.
