74HC02DB,112

Overview

The Nexperia 74HC02DB,112 is a quad 2-input NOR gate in the 74HC series. It operates on a supply voltage range of 2.0 V to 6.0 V and features CMOS low power dissipation with high noise immunity. The device includes input clamp diodes for interfacing voltages exceeding VCC. It provides latch-up performance exceeding 100 mA per JESD 78 Class II Level B and ESD protection exceeding 2000 V (HBM) and 1000 V (CDM). Operating temperatures span from -40 °C to +125 °C.

Feature Summary

• Quad 2-input NOR logic function
• Wide supply voltage range from 2.0 V to 6.0 V
• Input clamp diodes for overvoltage interfacing
• High noise immunity and robust latch-up performance

Applications

• General digital logic processing
• Mixed-signal circuit interfacing
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm package type and temperature range. Confirm current product status as availability may vary by region. Ensure compliance with RoHS3 specifications and JEDEC standards relevant to the application environment before finalizing procurement.

Selection Notes

Select this component for applications requiring standard CMOS NOR logic within a 2.0 V to 6.0 V supply range. Consider the SO14 package dimensions when designing PCB layouts. Verify that input signal levels align with CMOS switching thresholds specified in the datasheet for reliable operation across the full temperature range.

Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices manufactured by Nexperia. The 'DB' suffix indicates the SO14 plastic small outline package variant. It is distinct from the TSSOP or QFN packages available within the same logical family.
