SN74AHC08QDRG4Q1

Overview

The SN74AHC08QDRG4Q1 is an automotive-grade quad 2-input positive AND gate from the Texas Instruments SN74AHC08Q series. It operates within a supply voltage range of 2 V to 5.5 V and features low static current consumption of 2 µA. The device provides symmetrical output drive capabilities with 8 mA sink and source currents. It exhibits a propagation delay of 9 ns and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a 14-pin SOIC (D) format, it meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle environments
• High-speed logic performance with 9 ns propagation delay at 5 V
• Wide operating voltage support ranging from 2 V to 5.5 V
• Low power consumption with minimal static current draw

Applications

• Automotive electronic control units requiring robust logic gating
• In-vehicle infotainment system signal processing
• Body control module input conditioning
• Telematics unit data routing

Procurement Notes

Verify the complete part number including the suffix G4, which indicates specific manufacturing and packaging details. Confirm that the AEC-Q100 grade matches the specific automotive application requirements. Ensure the SOIC-14 package dimensions align with the target PCB footprint. Check for RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability is mandatory alongside high-speed logic operations. The AHC series offers superior speed compared to standard HC logic while maintaining low power characteristics. The 2 V to 5.5 V range allows compatibility with various automotive power rails. Consider the 14-SOIC package constraints for board space limitations. Verify thermal management needs given the +125°C maximum junction temperature rating.

Part Context

This device belongs to the SN74AHC08Q family of automotive quadruple 2-input AND gates. It shares functional similarities with other automotive logic ICs but distinguishes itself through AHC technology speed and voltage flexibility. The Q1 suffix denotes automotive qualification, while G4 specifies the tape-and-reel packaging configuration. It serves as a fundamental building block for digital logic circuits in harsh automotive environments.

Replacement Considerations

SN74AHC08DRG4Q1 is a verified substitute offering identical electrical characteristics and automotive qualification. SN74HC08QDRQ1 provides similar functionality but differs in speed and drive strength specifications. SN74AC08QDRG4Q1 offers higher drive current but requires careful voltage level consideration. Verify pinout compatibility and package dimensions before substituting any alternative part numbers.
