74AHC2G08DC-Q100H

Overview

The Nexperia 74AHC2G08DC-Q100H is a dual 2-input AND gate in the AHC logic family, qualified to AEC-Q100 Grade 1 for automotive use. It operates on a supply voltage of 2.0 V to 5.5 V with overvoltage tolerant inputs up to 5.5 V. The device features symmetrical output impedance and balanced propagation delays. Static characteristics include low power dissipation and high noise immunity. Dynamic performance at 3.3 V with 15 pF load shows typical propagation delay of 4.6 ns. ESD protection exceeds 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• Overvoltage tolerant inputs allow operation in mixed voltage environments.
• High noise immunity with CMOS low power dissipation.
• Robust ESD protection exceeding 2000 V HBM and 1000 V CDM.

Applications

• Automotive electronic systems requiring Grade 1 component qualification.
• Mixed voltage signal translation between different logic domains.
• General purpose digital logic processing in consumer electronics.

Procurement Notes

Verify the specific suffix 'H' against official Nexperia documentation to confirm packaging details such as reel or cut tape specifications. Ensure the ordering part number matches the required temperature range and package variant SOT765-1. Confirm compliance requirements including RoHS and REACH status directly from the manufacturer's latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when an automotive-grade dual AND gate is required within the AHC series. It is suitable for designs needing input tolerance above the supply rail. Compare against AHCT variants if TTL input levels are necessary instead of CMOS levels. Verify that the VSSOP8 package dimensions fit the PCB layout constraints for the SOT765-1 footprint.

Part Context

This device belongs to the Nexperia 74AHC_AHCT2G08_Q100 product family. It shares functional similarities with other single-function gates in the automotive portfolio. The DC suffix indicates the VSSOP8 plastic very thin shrink small outline package. It serves as a standard logic solution for embedded control applications in vehicles.

Replacement Considerations

The 74AHCT2G08DC-Q100H is a compatible alternative within the same package offering TTL input levels. Other AHC family members may serve as functional substitutes if pin compatibility is maintained. Verify electrical parameters match the design requirements before swapping components.

FAQ

What is the input voltage tolerance level?

The inputs are overvoltage tolerant up to 5.5 V, allowing safe interfacing with higher voltage signals even when the device operates at lower supply voltages.

Does this device support partial power-down mode?

The datasheet does not specify I_OFF circuitry for partial power-down operation in the 74AHC2G08-Q100; this feature is typically associated with the 74AUP series.
