74HC3G04DC-Q100H

Overview

The Nexperia 74HC3G04DC-Q100H is a triple inverter integrated circuit designed for automotive applications, qualified to AEC-Q100 Grade 1 standards. 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 CMOS low power dissipation, high noise immunity, and latch-up performance exceeding 100 mA per JESD 78 Class II Level B. Inputs include clamp diodes for interfacing with voltages exceeding VCC. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM). Propagation delay at 4.5 V is typically 8 ns.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 specifications
• Wide operating temperature range supporting -40 °C to +125 °C environments
• Integrated input clamp diodes enabling safe interface to voltages above VCC
• High electrostatic discharge protection exceeding 2000 V via Human Body Model

Applications

• Automotive electronic systems requiring robust logic inversion
• Signal conditioning and wave shaping in harsh environments
• Pulse generation circuits utilizing astable or monostable configurations

Procurement Notes

Verify the specific suffix DC corresponds to the VSSOP-8 package (SOT765-1) during procurement. Confirm that the required variant matches the HC logic family rather than HCT, as input levels differ significantly between CMOS and TTL compatibility. Ensure design margins account for the specified maximum propagation delays across the full temperature range.

Selection Notes

Select this component when a compact triple inverter solution is required for automotive-grade designs. The VSSOP-8 package offers space efficiency compared to standard TSSOP options. Consider the HC series for broader voltage flexibility down to 2.0 V, whereas HCT variants are restricted to higher voltage ranges. Verify that the static and dynamic characteristics meet the system's noise immunity and speed requirements.

Part Context

This part belongs to the Nexperia 74HC3G04-Q100 family of triple inverters. It shares functional similarities with other single-gate automotive logic devices like the 74AHC1G04GW-Q100H but provides three independent channels in a single package. The Q100 designation indicates its suitability for automotive electronics, distinguishing it from commercial-grade counterparts lacking extended temperature and reliability testing.

Replacement Considerations

Direct substitutes include the 74HCT3G04DC-Q100H if TTL-compatible inputs are acceptable. Other family members such as the 74HC3G04DP-Q100H offer identical functionality in a TSSOP-8 package. Cross-referencing pinouts and electrical parameters against existing designs is essential before substitution.
