SN74AHCT08QPWRG4Q1

Overview

The SN74AHCT08QPWRG4Q1 is an automotive-grade quadruple 2-input positive-AND gate manufactured by Texas Instruments. It belongs to the AHC (Advanced High-Speed CMOS) logic family, offering high-speed performance with low power consumption. The device operates within a supply voltage range of 4.5 V to 5.5 V and features TSSOP-14 surface-mount packaging. It is qualified under AEC-Q100 standards for automotive applications, ensuring reliability across an operating temperature range of -40°C to +125°C. Key electrical characteristics include a propagation delay of 7.9 ns at 5 V with 50 pF load, and output drive currents of ±8 mA.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for enhanced reliability in vehicle electronics.
• High-speed CMOS technology providing fast switching times while maintaining low static power dissipation.
• TTL-compatible input thresholds allowing direct interfacing with standard TTL logic devices.

Applications

• Automotive electronic control units requiring robust logic gating.
• Infotainment systems utilizing high-speed data processing.
• Body control modules managing multiple sensor inputs.

Procurement Notes

Verify the complete part number including the G4 suffix, which indicates lead-free and halogen-free compliance. Confirm that the specific variant matches the AHCT series requirements for 5V operation. Ensure the package type corresponds to the design footprint. Check for any recent product change notifications regarding manufacturing site updates or material substitutions.

Selection Notes

Select this component when designing for 5V automotive environments requiring precise AND logic functionality. The AHCT series is suitable where TTL compatibility is necessary alongside AHC speed benefits. Consider the TSSOP-14 package constraints for PCB layout. Evaluate thermal management needs given the extended temperature range capabilities.

Part Context

This part is part of Texas Instruments' SN74AHCxQ and SN74AHCTxQ families, specifically designed for automotive applications. It shares pinout compatibility with non-automotive counterparts but includes rigorous testing for automotive grade reliability. The 'Q1' suffix denotes automotive qualification, while 'G4' specifies environmental compliance.

Replacement Considerations

Direct substitutes include SN74AHCT08QPWRQ1. Verify if the G4 suffix is mandatory for regulatory compliance in the target application. Cross-reference with SN74AHCT08PW for non-automotive versions if automotive qualification is not required.
