74AHCT3G04DC-Q100H

Overview

The Nexperia 74AHCT3G04DC-Q100H is a triple inverter qualified to AEC-Q100 Grade 1 for automotive use. 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 is housed in an 8-lead VSSOP package (SOT765-1). It supports ambient temperatures from -40 °C to +125 °C, ensuring balanced propagation delays and high noise immunity.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input switching levels with overvoltage tolerance
• High noise immunity and CMOS low power dissipation

Applications

• Automotive electronic systems requiring robust logic inversion
• Mixed voltage environments utilizing TTL-to-CMOS translation
• Engine control units and body control modules

Procurement Notes

Verify the specific suffix 'Q100H' against official Nexperia documentation to confirm packaging details and regional availability. Ensure the design environment strictly adheres to the specified 4.5 V to 5.5 V supply voltage limits. Confirm that the VSSOP8 package dimensions align with the target PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when TTL-level compatibility is required alongside automotive reliability standards. The AHCT variant specifically targets 5 V logic families, distinguishing it from the broader voltage range AHC series. Verify that the operating temperature range meets the specific environmental requirements of the intended application zone.

Part Context

This part belongs to the Nexperia 74AHC_AHCT3G04-Q100 family of single-gate inverters. It shares functional characteristics with the 74AHC3G04DC-Q100 but differs in input threshold specifications. The DC suffix denotes the VSSOP8 plastic very thin shrink small outline package, providing a compact footprint suitable for space-constrained automotive designs.

Replacement Considerations

The 74AHC3G04DC-Q100H serves as a pin-compatible alternative if CMOS input thresholds are acceptable instead of TTL levels. Other members of the 74AHC_AHCT3G04-Q100 family may be considered based on specific voltage or package requirements.

FAQ

What is the difference between the 74AHCT3G04 and 74AHC3G04 variants?

The 74AHCT3G04 utilizes TTL input switching levels and operates at 4.5 V to 5.5 V, whereas the 74AHC3G04 uses CMOS input levels and supports a wider voltage range of 2.0 V to 5.5 V.

Does the device support partial power-down applications?

Yes, the datasheet specifies I_OFF circuitry which disables the output to prevent damaging backflow current when the device is powered down.
