74AHC3GU04DC-Q100H

Overview

The Nexperia 74AHC3GU04DC-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 functions across an ambient temperature range of -40 °C to +125 °C. The device features overvoltage tolerant inputs up to 5.5 V, CMOS input levels, and high noise immunity. Static characteristics include low power dissipation and latch-up performance exceeding 100 mA per JESD 78 Class II Level A. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Propagation delays are specified from 1.0 ns to 13.5 ns depending on load capacitance and voltage.

Feature Summary

Procurement Notes

Verify the specific ordering suffix 'H' against current Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the DC package variant matches the required PCB footprint constraints. Confirm that the AEC-Q100 Grade 1 qualification meets the specific reliability requirements of the target automotive application before finalizing procurement.

Selection Notes

Select this component when a triple inverter with automotive grade reliability is required. The wide supply voltage range supports both 3.3 V and 5 V logic families. Overvoltage tolerance allows direct interfacing without additional protection circuitry. Consider the VSSOP8 package dimensions for space-constrained designs. Verify thermal derating requirements if operating near maximum ambient temperatures.

Part Context

This part belongs to the 74AHC3GU04-Q100 family of triple unbuffered inverters. The DC designation indicates the VSSOP8 plastic very thin shrink small outline package (SOT765-1). This series provides high-speed switching capabilities suitable for automotive electronics while maintaining low static power consumption. The family includes variants with different package options to accommodate diverse layout requirements.

Replacement Considerations

The 74AHC3GU04DP-Q100 serves as a package alternative using the TSSOP8 format. Both devices share identical electrical specifications and functional behavior. Verify pin compatibility and physical footprint differences when substituting between the DC and DP package types.

FAQ
