74AHCT00BQ-Q100X

Overview

The Nexperia 74AHCT00BQ-Q100X is a quad 2-input NAND 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 accepts TTL-level inputs. The device features Schmitt-trigger action, overvoltage tolerant inputs up to 5.5 V, and balanced propagation delays. It is housed in a DHVQFN14 package (SOT762-1) with side-wettable flanks, supporting an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Automotive qualification compliant with AEC-Q100 Grade 1 standards
• TTL-compatible input levels with Schmitt-trigger action for noise immunity
• Overvoltage tolerant inputs enabling use as translators in mixed-voltage environments
• DHVQFN14 package design with side-wettable flanks facilitating automatic optical inspection

Applications

• Automotive electronic systems requiring robust logic gating
• Mixed-voltage signal translation between TTL and CMOS domains
• High-noise immunity digital circuit designs

Procurement Notes

Verify the specific suffix 'BQ' corresponds to the DHVQFN14 package variant during procurement. Confirm that the 'Q100' designation ensures compliance with AEC-Q100 Grade 1 automotive reliability requirements. Ensure the ordering quantity aligns with manufacturer packaging specifications for the selected tape-and-reel configuration.

Selection Notes

Select this component when TTL-level input compatibility is required alongside high-speed NAND logic functionality in automotive environments. The DHVQFN14 package is suitable for space-constrained PCB layouts requiring thermal enhancement and reliable solder joint inspection via AOI. Verify that the 4.5 V to 5.5 V operating voltage range matches the system power supply constraints.

Part Context

This part belongs to the Nexperia 74AHC/AHCT00-Q100 family of quad 2-input NAND gates. It shares functional characteristics with other members of the series but is distinguished by its AHCT input levels and BQ DHVQFN14 package. The family is designed for general-purpose logic applications with specific emphasis on automotive durability and mixed-signal interface capabilities.

Replacement Considerations

Direct substitutes include other 74AHCT00 variants in compatible packages such as SO14 or TSSOP14, provided pinout compatibility is maintained. Cross-reference with equivalent automotive-grade quad NAND gates from other manufacturers if package changes are permissible.
