74AHCT2G08DC-Q100H

Overview

The Nexperia 74AHCT2G08DC-Q100H is a dual 2-input AND gate qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates within a supply voltage range of 4.5 V to 5.5 V and features TTL input switching levels. The device utilizes an 8-lead VSSOP (SOT765-1) package with a body width of 2.3 mm. It supports ambient temperatures from -40 °C to +125 °C, includes overvoltage tolerant inputs up to 5.5 V, and provides symmetrical output impedance with balanced propagation delays.

Feature Summary

• Automotive qualification in accordance with AEC-Q100 Grade 1
• TTL input switching levels for compatibility with standard logic families
• Overvoltage tolerant inputs allowing use as translators in mixed voltage environments
• High noise immunity and CMOS low power dissipation

Applications

• Automotive electronic systems requiring Grade 1 component qualification
• Mixed voltage signal translation between TTL and CMOS domains
• Digital logic circuits operating at 5 V supply rails

Procurement Notes

Verify the specific suffix 'Q100H' matches the required automotive grade and tape-and-reel packaging configuration. Confirm that the VSSOP-8 package variant aligns with your PCB footprint requirements. Ensure design specifications account for the TTL input thresholds defined for the AHCT series rather than standard AHC CMOS levels.

Selection Notes

Select this component when TTL-compatible inputs are necessary within an automotive-grade environment. The AHCT series ensures direct interface with legacy TTL outputs without level shifting. Verify that the 4.5 V to 5.5 V supply range meets system power constraints. Consider the VSSOP-8 package dimensions if space optimization is critical compared to larger packages.

Part Context

This part belongs to the Nexperia 74AHC(AHCT)2G08-Q100 family of dual 2-input AND gates. The family includes variants with different input logic levels (AHC for CMOS, AHCT for TTL) and package options such as TSSOP and VSSOP. All members share AEC-Q100 Grade 1 qualification and extended temperature ranges suitable for demanding automotive environments.

Replacement Considerations

The 74AHC2G08DC-Q100H serves as a functional equivalent if CMOS input levels are acceptable instead of TTL. For identical TTL characteristics, the 74AHCT2G08DC-Q100H is the direct substitute. Other package versions like 74AHCT2G08DP-Q100H offer the same electrical performance in a TSSOP-8 housing.
