Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to ensure correct package type and tape/reel configuration. Confirm that the RoHS compliance status matches current regulatory requirements for the target market. Check for any recent product change notices regarding marking or assembly sites. Ensure the selected variant meets the required temperature grade specifications for the intended application environment.

Selection Notes

Select this component when an octal storage element with tri-state capability is required for bus architectures. The HCT series compatibility allows interfacing with TTL-level inputs while maintaining CMOS output characteristics. Consider the 20-pin SOP footprint for surface-mount assembly constraints. Evaluate the propagation delay and output drive strength against the system timing requirements and load conditions.

Part Context

This part belongs to the 74HC374 family of octal D-type flip-flops manufactured by Nexperia. It is part of the broader 74HC/HCT logic family designed for high-speed CMOS applications. The device complements other logic components such as latches and drivers within the same series. It is commonly used alongside similar flip-flops like the 74HC74 for complex sequential logic designs.

Replacement Considerations
