74ACT563SCX

Latches Overview

The Fairchild Semiconductor 74ACT563SCX is an octal D-type transparent latch featuring inverted outputs and three-state control. It operates within a supply voltage range of 4.5V to 5.5V and supports industrial temperature ranges from -40°C to 85°C. The device utilizes CMOS technology and is housed in a 20-pin SOIC package. It provides TTL-compatible inputs and offers high-speed performance with a propagation delay of 10.5ns at 5V with a 50pF load.

Latches Feature Summary

• Octal D-type transparent latch architecture with inverted outputs
• Three-state output capability for bus-oriented applications
• TTL-compatible input levels for direct interfacing
• High-speed CMOS construction ensuring low power consumption

Latches Applications

• Bus-oriented data storage systems
• High-speed digital logic circuits
• Industrial control interfaces requiring TTL compatibility

Latches Procurement Notes

Verify the specific suffix 'SCX' against official Fairchild documentation to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with current distributor listings to confirm availability and authenticity, as obsolete or alternative packages may exist.

Latches Selection Notes

Select this component when an octal latch with inverted outputs and three-state control is required. It is suitable for designs needing TTL-compatible inputs and high-speed operation within the ACT series specifications. Consider the SOIC-20 package constraints and ensure the 4.5V to 5.5V supply voltage aligns with the system power rails.

Latches Part Context

This component belongs to the 74ACT family of high-speed CMOS logic devices. It serves as the inverted-output variant of the standard 74ACT574 octal D-type flip-flop. The device is designed for demanding digital applications requiring reliable data latching and bus isolation capabilities within industrial temperature ranges.

Latches Replacement Considerations

The 74ACT563FCQR is a confirmed ceramic flatpack substitute offering identical logical functionality. Verify pinout compatibility and thermal management requirements when transitioning between plastic SOIC and ceramic DFP packages.
