74FCT823ATQG

Overview

The IDT74FCT823ATQG is a high-speed CMOS D-type flip-flop featuring nine functional circuits in a single package. It operates with positive edge triggering and provides three-state outputs for bus-oriented memory addressing. The device utilizes advanced dual-metal CMOS technology to achieve low power consumption while maintaining high-speed performance. It supports an industrial temperature range of -40°C to +85°C and is housed in a 24-pin SSOP surface-mount package.

Feature Summary

• Nine-function D-type flip-flop architecture for compact data storage
• Positive edge-triggered operation synchronized with clock signals
• Three-state outputs enabling efficient bus-driven system designs
• Industrial temperature rating suitable for demanding environments

Applications

• Memory address latching in computer systems
• I/O port buffering and interface control
• Bus driver implementations for data transmission
• Temporary data storage in digital logic circuits

Procurement Notes

Verify the specific suffix 'ATQG' against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the package dimensions with your PCB footprint library to guarantee mechanical fit during integration.

Selection Notes

Select this component when a high-density solution for multi-bit data storage is required within a limited board area. The nine-function configuration reduces component count compared to using multiple single-bit flip-flops. Consider the three-state output capability if the design involves shared data buses requiring isolation between active and inactive drivers.

Part Context

This part belongs to the 74FCT logic family, which serves as a fast CMOS replacement for older transistor-transistor logic (TTL) functions. The FCT series is characterized by its ability to operate at higher speeds with lower power dissipation than standard TTL equivalents. It is designed for applications requiring reliable data handling in complex digital systems.

Replacement Considerations

Check for direct substitutes such as the CY74FCT823 from Texas Instruments or equivalent Renesas variants. Verify that any replacement maintains the same 24-pin SSOP package and logical functionality. Confirm that voltage levels and output drive strengths are compatible with the existing circuit design.
