Procurement Notes
Verify component authenticity through authorized Nexperia distributors or certified partners. Confirm that the specific suffix matches the required package variant and quality grade. Request official datasheets and compliance certificates to ensure adherence to AEC-Q100 specifications and RoHS directives before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring eight-bit parallel data storage with synchronous reset capabilities. Ensure the system voltage aligns with the 2 V to 6 V operating range. Consider the DHVQFN-16 package dimensions for PCB layout constraints and verify thermal dissipation requirements for high-temperature environments up to 125 °C.
Part Context
This part belongs to the Nexperia 74HC series, known for high-speed CMOS operation with TTL-compatible inputs. The Q100 designation indicates automotive-grade qualification, ensuring enhanced reliability under harsh conditions. The BQ suffix specifies the DHVQFN-16 leadless package, optimizing board space while maintaining electrical performance for complex digital logic applications.
Replacement Considerations
Direct substitutes include other AEC-Q100 qualified octal D-type flip-flops from Nexperia or compatible manufacturers offering identical pinouts and logical functions. Verify equivalent voltage ranges, propagation delays, and package dimensions to ensure seamless integration without redesigning the host circuit board.
