SN74AHC02QPWRG4Q1

Overview

The SN74AHC02QPWRG4Q1 is a quad two-input positive-NOR gate from the Texas Instruments AHC logic family, designed for automotive applications. It operates within a supply voltage range of 2 V to 5.5 V and features low output drive currents of 8 mA at both high and low states. The device exhibits a propagation delay of 5.1 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a TSSOP-14 surface-mount format, it holds AEC-Q100 qualification.

Feature Summary

• Automotive-grade reliability with AEC-Q100 qualification
• Wide operating voltage range supporting 2 V to 5.5 V systems
• High-speed switching performance with low propagation delay
• Robust output drive capability for standard digital loads

Applications

• Automotive electronic control units
• Infotainment system logic interfaces
• Body control module signal processing
• Sensor interface circuits requiring NOR logic

Procurement Notes

Verify the complete part number including suffixes such as G4 and Q1 to ensure correct packaging and automotive qualification status. Confirm that the TSSOP-14 package matches your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure compatibility with your assembly process regarding moisture sensitivity levels and reflow profiles specified in the official datasheet.

Selection Notes

Select this component when automotive certification is mandatory for NOR gate implementations. The AHC series offers faster switching speeds compared to standard HC logic while maintaining CMOS power efficiency. Consider the 2 V minimum supply voltage if designing for lower power domains. Verify that the 5.1 ns propagation delay meets your timing constraints for the specific application speed requirements.

Part Context

This device belongs to the SN74AHC02-Q1 family of automotive-qualified logic gates. It shares the same logical function as the commercial SN74AHC02 but undergoes stricter testing and qualification processes to meet automotive reliability standards. The G4 suffix indicates lead-free and RoHS-compliant construction, aligning with modern environmental regulations for electronic components.

Replacement Considerations

Direct substitutes include other SN74AHC02 variants with automotive qualification, such as those in SOIC packages like SN74AHC02QDRQ1. Non-automotive equivalents like the standard SN74AHC02 may function electrically but lack the required automotive reliability certifications.
