CD74HC564M96

Overview

The CD74HC564M96 is an octal D-type flip-flop manufactured by Texas Instruments, belonging to the high-speed CMOS logic family. It features eight positive edge-triggered D-type flip-flops with three-state inverting outputs. The device operates within a supply voltage range of 2 V to 6 V and supports a wide operating temperature range from -55°C to +125°C. Packaged in a 20-SOIC (0.295", 7.50mm Width) format, it is designed for high-performance applications requiring reliable data storage and routing capabilities.

Feature Summary

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

Applications

• High-performance memory decoding systems
• Data-routing circuits in digital communication interfaces
• Parallel-to-serial conversion modules

Procurement Notes

Verify the specific ordering suffix 'M96' corresponds to the tape and reel packaging configuration as documented in the manufacturer's official datasheet. Confirm that the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the component meets the required RoHS compliance standards for your assembly process. Cross-reference the part number with the latest Texas Instruments product selection guide to confirm availability and manufacturing status.

Selection Notes

Select this component when an octal storage element with bus-compatible outputs is required. The three-state feature simplifies board layout by eliminating the need for additional buffer drivers. Consider the HC logic series compatibility with existing 5V or 3.3V systems. Evaluate the wide temperature range suitability for industrial environments. Compare propagation delays against system clock speeds to ensure timing margins are met.

Part Context

The CD74HC564M96 is part of Texas Instruments' extensive CD74HCxx series of high-speed CMOS logic devices. This series is known for its compatibility with standard TTL logic levels while offering improved speed and lower power consumption compared to older HC variants. The M96 suffix typically denotes a specific packaging variant, often associated with tape and reel delivery for automated surface-mount assembly processes.

Replacement Considerations

Direct substitutes may include other octal D-type flip-flops with three-state outputs from the same logic family, such as the CD74HC574 or CD74HC575, provided pinout compatibility is verified. Alternative manufacturers may offer equivalent parts under different part numbers, but electrical specifications and package dimensions must be strictly matched.
