Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm RoHS compliance details directly with the manufacturer or authorized distributors prior to procurement. Ensure design-in specifications match the latest product data sheet revision to avoid discrepancies in electrical characteristics or pin configurations.

Selection Notes

Select this component when a dual 4-input NOR gate is required within a 2.0 V to 6.0 V supply range. Consider its CMOS input levels and high noise immunity for environments requiring signal integrity. Verify that the SO14 package dimensions fit the PCB layout constraints. Evaluate the propagation delay characteristics against system timing requirements at the intended operating voltage.

Part Context

This part belongs to the 74HC series of logic ICs, which are standard complementary metal-oxide-semiconductor devices. The 74HC4002 specifically implements dual 4-input NOR functionality. It is designed for general-purpose digital applications where low power consumption and high noise immunity are critical. The device is part of Nexperia's extensive portfolio of logic components.

Replacement Considerations

Check for equivalent parts from other manufacturers offering the same 74HC logic family and dual 4-input NOR function. Ensure pin compatibility and electrical specifications match before substitution. Verify package type alignment if physical footprint constraints exist.
