IDT74FCT823CTQG

Overview

The IDT74FCT823CTQG is a high-speed CMOS logic device manufactured by Renesas Electronics, functioning as a nine-function positive-edge triggered D flip-flop. It operates within the 74FCT series architecture and utilizes a PDSO-24 surface-mount package. The component supports a nominal supply voltage of 5 V and features three-state outputs for bus driving applications. Designed for industrial temperature ranges from -40 °C to 85 °C, it provides a propagation delay of approximately 7.5 ns at nominal supply conditions with a load capacitance of 50 pF.

Feature Summary

• Provides nine independent positive-edge triggered D flip-flops in a single integrated circuit
• Features three-state outputs suitable for direct connection to system buses
• Utilizes CMOS technology for high-speed operation with low power consumption

Applications

• High-speed data storage and buffering in digital systems
• Bus driver circuits requiring multiple synchronized data latches
• Industrial control systems operating within extended temperature ranges

Procurement Notes

Verify current availability status as this component may be subject to end-of-life restrictions or discontinuation notices from the manufacturer. Confirm that the PDSO-24 package variant matches your PCB footprint requirements. Ensure compliance with RoHS directives and check for any specific environmental certifications required for your deployment environment before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring multiple synchronized data registers with bus-compatible outputs. The five-volt CMOS interface ensures compatibility with standard logic families. Consider the 7.5 ns propagation delay for timing analysis in high-frequency applications. Verify that the industrial temperature rating meets the operational environmental constraints of the target hardware platform.

Part Context

This part belongs to the 74FCT family of high-speed CMOS logic devices originally developed by Integrated Device Technology (IDT) and later acquired by Renesas Electronics. The 74FCT series bridges the performance gap between standard TTL and faster ECL technologies, offering speed comparable to LS-TTL with CMOS power efficiency. This specific model represents a multi-bit register configuration within that lineage.

Replacement Considerations

Consult official Renesas cross-reference documentation for verified equivalent parts. Generic substitutes may not match the specific pinout, electrical characteristics, or package dimensions of the original IDT component.
