Overview
The Nexperia 74HC02BZZ is a quad 2-input NOR gate in the 74HC series, housed in a DHXQFN14 (SOT8014-1) leadless package. It operates on a supply voltage range of 2.0 V to 6.0 V with CMOS low power dissipation and high noise immunity. The device features inputs with 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 (>2000 V HBM) and JS-002 class C3 (>1000 V CDM). It complies with JEDEC standards JESD8C and JESD7A, operating from -40 °C to +125 °C.

- Quad 2-input NOR logic function
- Wide supply voltage range from 2.0 V to 6.0 V
- CMOS low power dissipation and high noise immunity
- Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
Applications
- General digital logic applications
- Mixed voltage interface circuits
- Industrial control systems
Procurement Notes
Verify the exact ordering suffix against the manufacturer's current catalog, as 'BZZ' may denote specific tape-and-reel or packaging variants not explicitly detailed in the standard datasheet table. Confirm RoHS compliance status and ensure the DHXQFN14 package dimensions match your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a quad NOR gate is required in a compact, leadless form factor. The DHXQFN14 package offers thermal enhancement suitable for space-constrained designs. Ensure the application voltage falls within the 2.0 V to 6.0 V range and that the operating temperature aligns with the specified -40 °C to +125 °C range.
Part Context
This part belongs to the 74HC02 family of quad 2-input NOR gates manufactured by Nexperia. It shares functional compatibility with other 74HC02 variants but differs in physical packaging. The DHXQFN14 package provides a small footprint with no leads, utilizing exposed pads for thermal management and mechanical stability.
Replacement Considerations
Direct pin-compatible replacements include 74HC02BQ (DHVQFN14), 74HC02PW (TSSOP14), and 74HC02D (SO14). Verify package dimensions and thermal characteristics when substituting.
