74HC4002D,652

Overview

The Nexperia 74HC4002D,652 is a dual 4-input NOR gate manufactured in an SO14 plastic small outline package (SOT108-1). It operates within a supply voltage range of 2.0 V to 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features CMOS input levels, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Static characteristics include input leakage currents up to ±1 μA at 6.0 V and supply currents up to 40 μA under maximum temperature conditions.

Feature Summary

• Dual 4-input NOR logic function with clamp diodes on inputs for overvoltage interfacing
• High noise immunity and robust latch-up protection exceeding 100 mA
• Wide operating supply voltage range supporting 2.0 V to 6.0 V applications

Applications

• Digital logic circuits requiring NOR gate functionality
• Signal processing systems utilizing CMOS technology
• Industrial control environments requiring wide temperature operation

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC4002 series includes alternative packages such as TSSOP14. Confirm current product status directly with Nexperia or authorized distributors, as availability may vary by region. Ensure compliance with RoHS and REACH regulations relevant to your target market before finalizing procurement orders.

Selection Notes

Select this component when a dual 4-input NOR gate is required within standard CMOS logic families. Consider the SO14 package for through-hole or surface-mount compatibility depending on PCB layout constraints. Verify that the 2.0 V to 6.0 V supply range aligns with system power rails and that the -40 °C to +125 °C temperature rating meets environmental requirements.

Part Context

This part belongs to the Nexperia 74HC logic family, which provides high-speed CMOS performance compatible with standard TTL inputs where specified. The 74HC4002 specifically implements dual 4-input NOR gates, distinct from other logic functions like NAND or AND gates within the same series. It is designed for general-purpose digital applications requiring reliable switching characteristics.

Replacement Considerations

Check for equivalent parts from other manufacturers offering identical pinouts and electrical specifications. Verify that any substitute maintains the same SO14 package dimensions and thermal characteristics to ensure mechanical compatibility without redesigning the footprint.
