74HC564FP-E

Overview

The 74HC564FP-E is an octal D-type flip-flop manufactured by Renesas Electronics Corporation, belonging to the HC/UH series of logic integrated circuits. It features eight independent D-type flip-flops with three-state outputs, housed in a 16-pin PDSO (Small Outline) package compliant with EIAJ standards. The device operates within a supply voltage range of 2.0V to 6.0V and supports a wide operating temperature range from -40°C to +85°C. It includes a clock input for data storage and an output enable control for managing bus lines.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops for parallel data storage
• Three-state outputs allowing direct connection to system buses without additional buffering
• High-speed CMOS technology ensuring low power consumption and fast switching characteristics

Applications

• Parallel-to-serial data conversion interfaces
• Bus-oriented memory register applications
• Clocked data storage in digital control systems

Procurement Notes

Verify that the component matches the exact part number 74HC564FP-E to ensure correct pinout and functionality. Confirm the package type is PDSO16 and check for RoHS compliance status as per current manufacturer specifications. Ensure the supplier provides valid traceability documentation for original Renesas Electronics Corporation products to avoid counterfeit components.

Selection Notes

Select this component when an octal storage solution with high-impedance states is required for bus architectures. Consider the HC series speed and voltage compatibility against other logic families like HCT or LVC if specific interface requirements exist. Verify that the 16-pin footprint fits the target PCB layout constraints before finalizing the design.

Part Context

This component is part of the widely adopted 74HC logic family, known for its compatibility with standard TTL levels while offering improved noise immunity and lower power dissipation compared to older bipolar logic families. The FP suffix indicates a specific plastic small outline package variant suitable for surface-mount assembly processes.

Replacement Considerations

HD74HC564RPEL is a confirmed substitute part number offering identical functional specifications and pinout compatibility.
