Substitute Part Grouping Explanation
Substitution of the 74HC4075N,652 is determined by the following critical parameters:
- Logic Function: All substitutes must implement 3-channel, 3-input OR gate logic
- Electrical Specifications: Supply voltage range (2V ~ 6V), quiescent current (2 µA max), output current (5.2mA), and propagation delay (17ns @ 6V, 50pF) must be maintained
- Package Compatibility: 14-DIP through-hole package with 0.300" (7.62mm) pitch is required for direct board-level replacement
- Base Product Number: All substitutes share the 74HC4075 base designation, indicating functional equivalence within the 74HC logic family
Two substitute parts meet these criteria and are listed below.

Engineering Selection Recommendations
CD74HC4075E (Harris Corporation): This substitute provides complete electrical and mechanical compatibility with the 74HC4075N,652. Operating temperature range extends to -55°C, offering broader environmental coverage. However, this part is RoHS non-compliant and carries obsolete status. Selection is appropriate for legacy system reproduction where RoHS compliance is not a design requirement.
74HC4075D,652 (NXP Semiconductors): This substitute is the manufacturer-recommended alternative and carries active product status, ensuring continued availability and supply chain stability. As an NXP product, it maintains consistency with the original part manufacturer. This option is preferred for new designs, system updates, or applications requiring long-term component availability. Detailed electrical specifications are not provided in available documentation; verification against the original 74HC4075N,652 specifications is necessary prior to implementation.
Frequently Asked Questions (FAQ)
Q: Can the CD74HC4075E be used as a direct replacement for the 74HC4075N,652?
A: Yes. Both parts implement identical 3-channel, 3-input OR gate logic in 14-DIP packages with matching electrical specifications (2V ~ 6V supply, 2 µA quiescent current, 5.2mA output current, 17ns propagation delay). The CD74HC4075E operates across a wider temperature range (-55°C to 125°C versus -40°C to 125°C). RoHS compliance differs; the CD74HC4075E is non-compliant while the original is ROHS3 compliant.
Q: What is the difference between the 74HC4075N,652 and 74HC4075D,652?
A: Both share the 74HC4075 base product number and implement the same logic function. The primary distinction is product status: the 74HC4075N,652 is obsolete, while the 74HC4075D,652 is active. The 74HC4075D,652 is NXP's current-generation equivalent and is recommended for applications requiring long-term availability.
Q: Are there package differences between these substitutes?
A: The 74HC4075N,652 and CD74HC4075E both use 14-DIP through-hole packages with 0.300" (7.62mm) pitch, enabling direct board-level substitution without layout modifications. Package specifications for the 74HC4075D,652 are not provided in available data.
Q: Which substitute should be selected for new designs?
A: The 74HC4075D,652 is the appropriate choice for new designs due to its active product status and manufacturer recommendation. This ensures component availability throughout the design lifecycle and production phases.
Q: Can these parts be used interchangeably in the same circuit?
A: The CD74HC4075E and 74HC4075N,652 are electrically and mechanically interchangeable. Substitution of the 74HC4075D,652 requires confirmation that electrical specifications meet circuit requirements, as detailed parameters are not provided in available documentation.
