74HC02BQ-Q100,115

Overview

The Nexperia 74HC02BQ-Q100,115 is a quad 2-input NOR gate within the 74HC-Q100 automotive logic family. It operates on 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 a DHVQFN14 (SOT762-1) package with dimensions of 2.5 × 3 × 0.85 mm. It complies with JEDEC standards JESD8C and JESD7A, features ESD protection exceeding 2000 V (HBM) and 1000 V (CDM), and offers latch-up performance exceeding 100 mA per JESD 78 Class II Level B.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1 standard for reliable operation in vehicle environments.
• DHVQFN package equipped with side-wettable flanks to enable automatic optical inspection of solder joints.
• Input clamp diodes allow interfacing inputs to voltages exceeding VCC using current limiting resistors.

Applications

• Engine control units
• Body control modules
• Transmission control units

Procurement Notes

Verify that the specific ordering suffix matches the required package variant. Confirm the exact grade and temperature rating aligns with the target application environment. Ensure compliance with relevant JEDEC standards is documented for the specific batch. Check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a quad NOR gate is required for automotive-grade applications operating between 2.0 V and 6.0 V. The DHVQFN14 package is suitable for designs requiring compact footprints with thermal enhancement capabilities. Consider input compatibility requirements, as the HC variant adheres to CMOS logic levels rather than TTL levels found in HCT counterparts.

Part Context

This part belongs to the 74HC-Q100 series, which provides robust logic functions specifically qualified for automotive electronics. The series includes various gates and flip-flops designed to meet stringent reliability standards. The 74HC02 variant specifically delivers four independent two-input NOR logic functions within a single integrated circuit package.

Replacement Considerations

The 74HCT02BQ-Q100 serves as a functional substitute with identical pinouts but different input voltage thresholds. Other packages such as SO14 or TSSOP14 offer alternative form factors for the same logical function.
