74HC02D,652

Overview

The Nexperia 74HC02D,652 is a quad 2-input NOR gate from the 74HC series. It operates within 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. Latch-up performance exceeds 100 mA per JESD 78 Class II Level B. ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 (HBM > 2000 V) and JS-002 class C3 (CDM > 1000 V). It complies with JEDEC standards JESD8C and JESD7A. Operating temperature ranges from -40 °C to +125 °C. The component is housed in an SO14 plastic small outline package (SOT108-1) with a body width of 3.9 mm.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product data sheet to confirm package type and temperature range specifications. Confirm RoHS compliance status and check for any recent Product Change Notices regarding marking or assembly updates. Ensure design-in compatibility with existing system voltage levels and load requirements before finalizing procurement plans.

Selection Notes

Select this component when a quad NOR gate configuration is required within standard CMOS logic families. Verify that the application voltage falls within the 2.0 V to 6.0 V operating range. Consider the SO14 package dimensions for PCB layout constraints. Ensure ESD protection requirements align with the specified HBM and CDM ratings for the target environment.

Part Context

This part belongs to the Nexperia 74HC/HCT logic family, which provides standard digital logic functions using CMOS technology. The 74HC series is characterized by wide supply voltage operation and compatibility with various logic families. The 'D' designation indicates the SO14 surface-mount package variant, while the ',652' suffix typically denotes specific packaging or tape-and-reel configurations defined by the manufacturer.

Replacement Considerations

Cross-reference with other 74HC02 variants from different manufacturers ensuring pinout and electrical characteristics match. Verify package compatibility if substituting with TSSOP or QFN versions.
