Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC4002 series is available in multiple configurations including SO14, SSOP14, and TSSOP14. Confirm that the DIP14 variant aligns with your PCB footprint requirements. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Check the latest product status on the manufacturer's website to confirm availability and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a dual 4-input NOR gate is required within a wide supply voltage range of 2.0 V to 6.0 V. It is suitable for designs needing high noise immunity and robust latch-up protection. Consider the DIP14 package for through-hole mounting applications. Verify that the CMOS input levels are compatible with the driving logic family in your circuit design.

Part Context

The 74HC4002 belongs to the 74HC (High-speed CMOS) logic family, designed for general-purpose digital applications. It offers compatibility with standard TTL logic levels while maintaining low power consumption typical of CMOS technology. The device is part of a broader portfolio of logic gates provided by NXP Semiconductors, ensuring interchangeability with other components in the same family for system expansion or replacement.

Replacement Considerations

Direct replacements include other 74HC4002 variants from different manufacturers that meet JEDEC JESD7A standards. Ensure the substitute component supports the same DIP14 package and electrical characteristics, particularly the supply voltage range and input/output levels. Verify thermal performance and ESD protection ratings match the original specifications.
