74AHCT3G04DP-Q100H

Overview

The Nexperia 74AHCT3G04DP-Q100H is a triple inverter qualified to AEC-Q100 Grade 1 for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels with overvoltage tolerant inputs up to 5.5 V. The device utilizes a TSSOP8 (SOT505-2) package and supports an ambient temperature range from -40 °C to +125 °C. Propagation delay is specified at 6.7 ns maximum at 4.5 V with 15 pF load, and 7.7 ns maximum at 50 pF load.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input switching levels with overvoltage tolerance up to 5.5 V
• Balanced propagation delays and symmetrical output impedance
• ESD protection exceeding 2000 V HBM and 1000 V CDM

Applications

• Automotive logic circuits requiring Grade 1 qualification
• Mixed voltage signal translation between TTL and CMOS domains
• High noise immunity digital signal inversion

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current ordering information to confirm tape-and-reel packaging specifications. Ensure the design accounts for the 4.5 V minimum supply voltage requirement inherent to the AHCT logic family. Confirm that the TSSOP8 package thermal characteristics align with the application's power dissipation limits under maximum ambient temperature conditions.

Selection Notes

Select this component when TTL-level inputs are required alongside high-speed performance in automotive environments. The AHCT series provides CMOS low power dissipation while maintaining compatibility with standard TTL logic families. Verify that the 5.5 V maximum input voltage rating matches the system's highest potential signal levels to ensure safe operation without external level shifting.

Part Context

This device belongs to the Nexperia 74AHC/AHCT 3G04-Q100 family of triple inverters designed for automotive use. It shares functional similarities with the 74AHC3G04 variant but differs in input threshold requirements, utilizing TTL levels instead of CMOS levels. The product line emphasizes robust ESD protection and latch-up performance suitable for harsh automotive electrical environments.

Replacement Considerations

The 74AHC3G04DP-Q100H serves as a compatible alternative if the application can accommodate CMOS input thresholds rather than TTL levels. Both devices share identical pinouts, package types, and automotive qualifications. Designers must verify that the system signals meet the higher VIH requirements of the AHC variant before substitution.

FAQ

What is the difference between the 74AHCT3G04 and 74AHC3G04 input specifications?

The 74AHCT3G04 features TTL input switching levels, whereas the 74AHC3G04 utilizes CMOS input switching levels. Both devices offer overvoltage tolerant inputs up to 5.5 V.

Is the 74AHCT3G04DP-Q100H suitable for life-critical automotive safety systems?

No. Unless explicitly agreed in writing, the product is not designed, authorized, or warranted for use in life support, life-critical, or safety-critical systems where failure could result in personal injury or death.
