74AHCT00BQ-Q100X

Overview

The 74AHCT00BQ-Q100X is a quad 2-input NAND gate manufactured by Nexperia, part of the AHCT logic family. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a DHVQFN-14 package (SOT762). The component holds AEC-Q100 Grade 1 qualification for automotive applications, ensuring reliability under specified temperature conditions.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• High noise immunity due to CMOS low power dissipation characteristics
• Overvoltage tolerant inputs compatible with mixed-voltage environments

Applications

• Automotive electronic control units
• Mixed-signal circuit interfacing
• General-purpose digital logic processing

Procurement Notes

Verify the manufacturer designation on official documentation, as the model originates from Nexperia despite the requested brand. Confirm the specific suffix 'X' corresponds to the correct tape-and-reel packaging configuration. Ensure the AEC-Q100 Grade 1 rating matches the project's environmental requirements before finalizing procurement orders.

Selection Notes

Select this component when a quad NAND gate is required for automotive systems operating at 5 V. The AHCT series ensures compatibility with standard TTL logic levels while offering improved performance over older HCT variants. The DHVQFN-14 package provides a compact solution for space-constrained printed circuit board designs.

Part Context

This device belongs to the Nexperia 74AHCT series of high-speed CMOS logic gates. The series is designed to bridge the gap between HC and HCT logic families, providing robust performance in automotive and industrial environments where strict quality and reliability standards are mandated by industry regulations.

Replacement Considerations

Cross-reference with other 74AHCT00 variants in the DHVQFN-14 package. Verify pinout compatibility and electrical specifications against alternative suppliers to ensure functional equivalence without redesigning the host circuit.
