74HC3GU04DC-Q100H

Overview

The Nexperia 74HC3GU04DC-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 6.0 V and supports ambient temperatures from -40 °C to +125 °C. The device features symmetrical output impedance, high noise immunity, and low power dissipation. Propagation delays are balanced with typical values of 13 ns at 2.0 V, 6 ns at 4.5 V, and 5 ns at 6.0 V. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications.
• Wide operating temperature range supporting -40 °C to +125 °C environments.
• High noise immunity with symmetrical output impedance characteristics.

Applications

• Linear amplifier circuits
• Crystal oscillator configurations

Procurement Notes

Verify the specific package variant against the ordering information table. The DC suffix indicates the VSSOP8 package (SOT765-1), while DP denotes TSSOP8 (SOT505-2). Confirm that the required temperature grade matches the specified -40 °C to +125 °C operational limits before finalizing procurement orders.

Selection Notes

Select this component when a triple inverter function is required in space-constrained automotive designs. The VSSOP8 package offers a very thin profile suitable for compact layouts. Ensure input voltages do not exceed the absolute maximum ratings to prevent damage to the internal clamp diodes.

Part Context

This part belongs to the 74HC3GU04-Q100 family of triple unbuffered inverters. It shares functional logic with other members but differs in physical packaging. The DC suffix specifically identifies the VSSOP8 plastic very thin shrink small outline package variant manufactured by Nexperia.

Replacement Considerations

The 74HC3GU04DP-Q100H serves as a direct functional substitute utilizing the TSSOP8 package instead of VSSOP8. Verify pin compatibility and thermal derating requirements when switching between these package types.

FAQ

Can the inputs interface with voltages exceeding VCC?

Yes, the inputs include clamp diodes which allow the use of current limiting resistors to interface inputs to voltages higher than the supply voltage.

What is the maximum quiescent supply current?

The maximum quiescent supply current is limited to 50 mA according to the absolute maximum rating system.
