74HC02BQ,115

Overview

The 74HC02BQ,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 the DHVQFN14 package (SOT762-1), featuring a body size of 2.5 × 3 × 0.85 mm with no leads. Static characteristics include high-level output voltages up to 5.9 V at 6.0 V supply and low-level output voltages down to 0.1 V. Dynamic performance specifies propagation delays of 15 ns maximum at 6.0 V with 50 pF load.

Feature Summary

• CMOS technology providing low power dissipation and high noise immunity
• Inputs equipped with clamp diodes for interfacing with voltages exceeding VCC
• Latch-up performance exceeds 100 mA per JESD 78 Class II Level B
• ESD protection compliant with ANSI/ESDA/JEDEC JS-001 class 2 and JS-002 class C3

Applications

• General-purpose logic circuits requiring NOR functionality
• Mixed voltage environments utilizing current limiting resistors on inputs
• Industrial applications operating across extended temperature ranges

Procurement Notes

Verify the specific ordering suffix matches the required package type, as the 74HC02 family includes multiple variants such as SO14, TSSOP14, and DHXQFN14. Confirm that the DHVQFN14 designation corresponds to the SOT762-1 outline in official documentation. Ensure compatibility with JEDEC standards JESD8C and JESD7A for the intended supply voltage conditions before finalizing procurement specifications.

Selection Notes

Select this component when a quad NOR gate configuration is required in a leadless thermal enhanced package. The DHVQFN14 form factor offers space efficiency compared to traditional plastic small outline packages. Consider the input clamp diode feature if direct interfacing to higher voltage sources without additional level shifting components is necessary. Verify that the 2.0 V to 6.0 V supply range aligns with system power rails.

Part Context

This part belongs to the 74HC02/74HCT02 family of quad 2-input NOR gates produced by Nexperia. The HC variant ensures CMOS compatibility with standard logic levels. The BQ suffix specifically identifies the DHVQFN14 package option, distinguishing it from other available packages like the PW (TSSOP14) or D (SO14) versions within the same logical family.

Replacement Considerations

Direct pin-compatible replacements within the same package family include the 74HCT02BQ for TTL-level input requirements. Other manufacturers may offer equivalent quad NOR gates in DHVQFN14 packages, but verification of static and dynamic electrical parameters against the Nexperia datasheet is essential.
