74HCT02BZZ

Overview

The Nexperia 74HCT02BZZ is a quad 2-input NOR gate in the 74HCT logic family. It operates on a supply voltage range of 4.5 V to 5.5 V with TTL input levels. The device features clamp diodes for overvoltage interfacing and high noise immunity. It is housed in a DHXQFN14 package (SOT8014-1) with dimensions of 2 mm x 2 mm x 0.48 mm. The component supports an ambient temperature range from -40 °C to +125 °C and complies with JEDEC standards JESD8C and JESD7A.

Feature Summary

• Quad 2-input NOR logic function
• TTL-compatible input levels
• High noise immunity and latch-up protection
• Extreme thin leadless QFN package

Applications

• Digital logic signal processing
• General-purpose NOR operations
• Industrial control systems

Procurement Notes

Verify the specific ordering suffix matches the required package variant, as the base part number covers multiple packages. Confirm the manufacturer source directly through authorized distributors or Nexperia sales channels. Ensure compliance with RoHS3 and REACH regulations for your region. Check the latest datasheet revision for any updates to pinning or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a compact, low-profile solution is required for NOR logic applications. The HCT series ensures compatibility with standard TTL logic families while offering CMOS power efficiency. The DHXQFN14 package provides thermal enhancement suitable for dense PCB layouts. Verify that the operating voltage remains within the specified 4.5 V to 5.5 V range for proper functionality.

Part Context

This component belongs to the Nexperia 74HCT02 family of quad 2-input NOR gates. It shares functional similarities with other variants like the 74HCT02D and 74HCT02PW but differs in physical packaging. The BZZ suffix specifically denotes the DHXQFN14 package type, which is distinct from SO or TSSOP options available in the same product line.

Replacement Considerations

Direct replacements include other 74HCT02 variants such as 74HCT02D or 74HCT02PW if package adaptation is feasible. Cross-package substitution requires verifying pinout compatibility and ensuring the new package meets thermal and mechanical constraints of the design.
