74HC02DB,118

Overview

The 74HC02DB,118 is a quad 2-input NOR gate manufactured by Nexperia USA Inc. It operates within a supply voltage range of 2.0 V to 6.0 V and supports an ambient temperature range from -40 °C to +125 °C. The device utilizes CMOS technology for low power dissipation and high noise immunity. It features inputs with clamp diodes to interface with voltages exceeding VCC. The component is housed in a SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Feature Summary

• CMOS low power dissipation
• High noise immunity
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• Inputs include clamp diodes

Applications

• Logic circuit design requiring NOR functionality
• Mixed voltage environments utilizing input clamp diodes
• Industrial applications operating at extended temperatures

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and availability status. Confirm that the SO14 package variant matches the intended PCB footprint requirements. Check for any recent product change notices regarding manufacturing location or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when a quad 2-input NOR gate is required with wide supply voltage flexibility. Ensure the application environment stays within the specified -40 °C to +125 °C temperature range. Consider the SO14 package dimensions if space constraints align with the SOT108-1 outline specifications.

Part Context

This part belongs to the 74HC/HCT logic family, specifically the 74HC02 series. It serves as a standard digital logic gate providing four independent NOR functions. The 'DB' designation indicates the SO14 package configuration, distinguishing it from other variants like TSSOP or QFN packages available within the same logical function family.
