QS74FCT823ATP

Flip Flops Overview

The QS74FCT823ATP is a high-speed CMOS logic device belonging to the FCT series, manufactured by Quality Semiconductor. It functions as a D Flip-Flop with nine independent functional units, designed for positive edge triggering applications. The component utilizes complementary metal-oxide-semiconductor (CMOS) technology and is housed in a PDSO24 surface-mount package. Key electrical parameters include a typical propagation delay of 7.5 ns at nominal supply voltage, an operating temperature range from -40 °C to 85 °C, and a standard supply voltage of 5 V. The device features three-state outputs and supports a load capacitance of 50 pF.

Flip Flops Feature Summary

• Nine independent positive edge-triggered D flip-flop units integrated into a single package
• Three-state output capability for efficient bus interfacing and system flexibility
• High-speed CMOS construction providing low power consumption and fast switching performance

Flip Flops Applications

• Parallel data storage and temporary holding in digital systems
• Shift register implementations requiring multiple stages
• Timing control circuits and sequential logic design

Flip Flops Procurement Notes

Verify the specific manufacturer source, as this part number appears in databases linked to Rochester Electronic and other distributors alongside original Quality Semiconductor documentation. Confirm that the PDSO24 package matches your PCB footprint requirements. Ensure the industrial temperature rating (-40°C to 85°C) aligns with your environmental specifications. Cross-reference the pinout against official datasheets to avoid compatibility issues with similar FCT series devices.

Flip Flops Selection Notes

Select this component when a high density of flip-flops is required in a compact surface-mount form factor. The nine-function configuration reduces board space compared to using multiple single flip-flop ICs. Consider the 7.5 ns propagation delay for timing constraints in your circuit design. Verify that the 5V supply voltage and CMOS input levels are compatible with your system's logic family.

Flip Flops Part Context

This device is part of the broader FCT (Fast CMOS) logic family, which serves as a high-speed, low-power replacement for older bipolar logic families like the 74F series. The FCT series is characterized by its ability to interface directly with TTL inputs while offering significantly faster switching speeds and lower power dissipation. This specific model focuses on sequential logic functionality within that high-performance ecosystem.
