74AHC3GU04DP-Q100H

Overview

The Nexperia 74AHC3GU04DP-Q100H is a triple unbuffered inverter qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V, enabling use in mixed-voltage environments. The device utilizes TSSOP8 (SOT505-2) packaging with three independent inverters. Static characteristics include low input leakage current and high noise immunity. Dynamic performance specifies propagation delays ranging from 1.0 ns to 13.5 ns depending on load capacitance and supply voltage.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Overvoltage tolerant inputs allowing operation in mixed voltage systems
• Symmetrical output impedance with balanced propagation delays
• High noise immunity and CMOS low power dissipation

Applications

• Linear amplifier circuits
• Crystal oscillator designs
• Signal inversion in mixed voltage logic interfaces

Procurement Notes

Verify the specific suffix DP indicates the TSSOP8 package variant during procurement. Confirm that the Q100 designation aligns with required automotive grade specifications. Ensure ordering quantities match distributor reel requirements. Cross-reference the manufacturer part number with official Nexperia documentation to validate authenticity and revision status before finalizing purchase orders.

Selection Notes

Select this component when a triple inverter configuration is required for automotive-grade reliability. The wide supply voltage range supports both 3.3 V and 5 V logic families. Overvoltage tolerance simplifies interface design between different voltage domains without additional level shifting components. Consider thermal derating limits if operating near maximum ambient temperatures.

Part Context

This device belongs to the 74AHC3GU04-Q100 family of triple unbuffered inverters. It shares functional similarities with other single-gate or multi-gate inverters but provides three channels in a compact surface-mount package. The AHC logic family offers higher speed compared to standard HC series while maintaining low power consumption suitable for battery-operated automotive electronics.

Replacement Considerations

Direct substitutes include the 74AHC3GU04DC-Q100H which uses a VSSOP8 package. Verify pin compatibility and thermal characteristics when substituting packages. Other AHC family inverters may require redesigning the circuit layout due to differing gate counts or pin configurations.
