74HC574BQ-Q100X

Overview

The 74HC574BQ-Q100X is an octal D-type flip-flop with three-state outputs, manufactured by Nexperia USA Inc. It belongs to the 74HC logic family and is housed in a DHVQFN-14 package (SOT763). The component is qualified to AEC-Q100 Grade 1 standards for automotive applications. It operates on a supply voltage range of 2.0 V to 6.0 V and supports a working temperature range from -40°C to +125°C. The device features push-pull outputs and includes Schmitt-trigger action on all inputs.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Octal configuration providing eight independent D-type flip-flops
• Three-state output capability for efficient bus driving
• Wide operating voltage range supporting diverse system requirements

Applications

• Automotive data acquisition systems
• Industrial control logic interfaces

Procurement Notes

Verify the specific suffix 'X' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the DHVQFN-14 package dimensions match your PCB footprint requirements. Confirm that the AEC-Q100 Grade 1 rating aligns with your thermal and reliability targets. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when an octal storage solution with high noise immunity is required. The HC series offers standard CMOS performance suitable for general-purpose digital logic. Consider the DHVQFN-14 package for space-constrained designs requiring surface-mount technology. Verify input voltage levels match your system's logic family to ensure proper interface compatibility without additional level shifting.

Part Context

This part is part of Nexperia's extensive portfolio of automotive-qualified logic ICs. It complements other devices in the 74HC and 74HCT families, offering standardized functionality across various package types. The product line supports global manufacturing and distribution networks, ensuring availability for mass production environments while maintaining consistent quality standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the same logic family. Verify electrical parameters such as propagation delay and output current capabilities. Ensure the replacement maintains the same AEC-Q100 qualification level if automotive use is intended.
