74AHCT2G00DC-Q100H

Overview

The Nexperia 74AHCT2G00DC-Q100H is a high-speed Si-gate CMOS dual 2-input NAND gate 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. The device is housed in an SOT765-1 (VSSOP8) package, supporting ambient temperatures from -40 °C to +125 °C. Key electrical characteristics include symmetrical output impedance, low power dissipation, and balanced propagation delays. ESD protection exceeds 2000 V (HBM Class 2) and 1000 V (CDM Class C3).

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards.
• TTL-compatible input switching levels for direct interfacing with TTL logic.
• High noise immunity and symmetrical output impedance.
• Robust electrostatic discharge protection exceeding JEDEC Class 2 and Class C3 thresholds.

Applications

• Automotive electronic systems requiring Grade 1 component qualification.
• Mixed-voltage logic translation between TTL and CMOS domains.
• Signal processing circuits utilizing dual 2-input NAND functionality.

Procurement Notes

Verify the specific suffix 'H' against the manufacturer's current ordering information to confirm packaging details such as reel or cut tape configuration. Ensure the design accommodates the VSSOP8 package dimensions and thermal derating requirements specified in the datasheet. Confirm that the application environment remains within the -40 °C to +125 °C operating temperature range to maintain guaranteed performance specifications.

Selection Notes

Select this component when TTL-level inputs are required alongside CMOS output drive capabilities in a compact surface-mount form factor. The AHCT series is appropriate for designs needing compatibility with legacy TTL signaling while benefiting from modern CMOS speed and power efficiency. The Q100 qualification makes it suitable for automotive environments where higher reliability grades are mandated compared to standard commercial grade parts.

Part Context

This part belongs to the Nexperia 74AHC/AHCT2G00-Q100 family of dual 2-input NAND gates. The family includes variants with different input levels (CMOS vs. TTL) and packages (TSSOP8 vs. VSSOP8). The DC variant specifically denotes the VSSOP8 package, distinguishing it from the DP TSSOP8 version. All family members share the same core logical function and automotive qualification status.

Replacement Considerations

The 74AHC2G00DC-Q100H serves as a CMOS-input equivalent within the same package and qualification class. For non-automotive applications, the 74AHCT2G00DC without the Q100 suffix may be considered if automotive qualification is not required. Verify pinout compatibility and voltage level requirements before substituting.
