74FCT823CTQG

Overview

The IDT 74FCT823CTQG is a high-speed CMOS logic device belonging to the FCT series, functioning as a nine-bit D-type flip-flop. It features positive edge triggering and provides three-state outputs for effective bus management in digital systems. The component operates with a nominal supply voltage of 5V and supports surface-mount installation. Key electrical characteristics include a propagation delay of 7.5 ns at nominal supply and a load capacitance rating of 50 pF. Designed for industrial temperature ranges from -40°C to 85°C, it utilizes a 24-pin SSOP package.

Feature Summary

• Positive edge triggered D-type flip-flop architecture
• Three-state output capability for bus interfacing
• Industrial temperature range operation

Applications

• High-speed data storage circuits
• Parallel interface buffering

Procurement Notes

Verify the specific manufacturer source, as this part number appears across multiple vendors including Renesas and Texas Instruments due to industry acquisitions. Confirm the exact package variant and suffix codes match your design requirements. Check current lifecycle status, as availability varies significantly by supplier. Ensure compatibility with existing PCB footprints and verify RoHS compliance documentation before finalizing procurement decisions.

Selection Notes

Select this component when a nine-bit parallel storage element with tri-state outputs is required. The FCT series offers faster switching speeds compared to standard TTL equivalents while maintaining compatible logic levels. Consider the 7.5 ns propagation delay for timing analysis. Verify that the 5V supply voltage aligns with the system power rails and that the SSOP package fits the available board space constraints.

Part Context

This device is part of the broader 74FCT family of high-speed CMOS logic ICs originally developed by Integrated Device Technology. The family is characterized by fast switching speeds and compatibility with TTL inputs. IDT was later acquired by Renesas Electronics, which continues to manufacture and distribute these components under the Renesas brand name alongside legacy IDT markings.

Replacement Considerations

Cross-reference with CY74FCT823ATSOCT from Texas Instruments or 74FCT823BTQ from other manufacturers. Verify pinout compatibility and electrical specifications such as propagation delay and output drive strength. Ensure the replacement part matches the required package type and operating temperature range.
