• Inverted outputs available for direct interfacing with complementary logic requirements
• Rising-edge triggered operation ensures precise data synchronization
• Wide operating voltage range supports compatibility with diverse system power supplies

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations in communication interfaces
• General-purpose storage elements in microprocessor systems
• Timing control and state machine architectures

Procurement Notes

Verify the manufacturer designation carefully, as the standard product business formerly belonging to NXP is now operated by Nexperia. Confirm that the component meets current RoHS compliance standards required for your specific application region. Ensure the ordering suffix matches the exact package type needed for your PCB layout. Check availability status directly with authorized distributors as supply conditions may vary.

Selection Notes

Select this component when an octal storage solution with inverted outputs is required. It is suitable for designs needing wide voltage tolerance between 2 V and 6 V. Consider the DIP-20 package constraints for through-hole assembly processes. Evaluate propagation delay specifications against your system clock speed requirements to ensure timing margins are sufficient for reliable operation.

Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. The series is known for replacing older TTL technologies with lower power consumption and higher noise immunity. The 74HC564 specifically addresses applications requiring multiple synchronized storage elements with inverted polarity outputs, fitting into standard industrial and consumer electronic design frameworks.

Replacement Considerations

Check for equivalent parts from Nexperia or other manufacturers offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same inverted output configuration and voltage range. Ensure the replacement package matches the physical footprint and thermal requirements of the original design.
