• Data synchronization between asynchronous domains

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature grade. Confirm RoHS compliance status and lead time requirements directly with authorized distributors prior to procurement. Ensure the selected variant matches the required pinout and electrical specifications for the target application design.

Selection Notes

Select this component when dual independent flip-flops are required in a compact surface-mount package. Consider the wide voltage range for compatibility with various logic families. Evaluate the propagation delay characteristics against system timing requirements. Verify that the input capacitance and drive capabilities meet the source and load interface specifications.

Part Context

This part belongs to the Texas Instruments CD74HC series of high-speed CMOS logic devices. It is designed for general-purpose digital applications requiring reliable state storage and transfer. The device complements other components in the 74HC family, offering standardized pinouts and electrical characteristics for easy integration into complex digital systems.

Replacement Considerations

Compatible substitutes include the SN74HC74N or SN74HC74DR from Texas Instruments, provided the package type and pinout match the design requirements. Other manufacturers may offer equivalent parts under different naming conventions, but electrical parameters must be verified for compatibility.
