74AHC74BQ-Q100X

Overview

The Nexperia 74AHC74BQ-Q100X is a dual D-type flip-flop with reset, belonging to the AHC logic family. It features a DHVQFN-14 package and holds AEC-Q100 Grade 1 qualification for automotive applications. The device operates within a supply voltage range of 2.0 V to 5.5 V. It supports direct interface with TTL levels and includes Schmitt trigger action on all inputs for noise immunity. The component is designed for partial power-down applications via I_OFF circuitry and offers high ESD protection capabilities.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Dual D-type flip-flops with independent reset functionality
• Schmitt trigger inputs ensure tolerance to slow signal transitions
• I_OFF circuitry prevents damaging backflow current during partial power-down

Applications

• Automotive electronic control units requiring robust logic storage
• Mixed-signal systems interfacing 3.3 V or 5 V devices
• Data acquisition systems utilizing parallel data latching
• Industrial automation controllers demanding high noise immunity

Procurement Notes

Verify that the specific suffix BQ corresponds to the DHVQFN-14 package variant required for your PCB footprint. Confirm AEC-Q100 Grade 1 qualification aligns with your automotive thermal requirements. Ensure design compatibility with the specified 2.0 V to 5.5 V operating range. Check for RoHS compliance status if environmental regulations apply to your region.

Selection Notes

Select this component when dual D-type flip-flops are needed in a compact surface-mount format. It is suitable for designs requiring direct TTL level interfacing without additional buffering. Consider this part for automotive environments where AEC-Q100 certification is mandatory. Evaluate the DHVQFN-14 package constraints against your available board space and thermal dissipation needs.

Part Context

This component belongs to Nexperia's 74AHC series, which provides high-speed CMOS performance with low power consumption. The -Q100 designation indicates automotive qualification, ensuring suitability for harsh operating conditions. The BQ suffix specifies the DHVQFN-14 package type, offering a small form factor for dense circuit layouts.

Replacement Considerations

Cross-reference with other 74AHC74 variants from different manufacturers ensuring identical pinout and electrical characteristics. Verify that substitute parts also hold AEC-Q100 qualification if automotive use is intended. Confirm package dimensions match the DHVQFN-14 specification to avoid mechanical interference.
