Procurement Notes

Verify the specific suffix 'CTSOG' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement channel sources genuine Renesas or IDT branded components to guarantee electrical parameter compliance. Cross-reference the RoHS status and lead times directly with authorized distributors prior to ordering.

Selection Notes

Select this component when an octal D-flip-flop with integrated master reset is required for 5V logic applications. The high output drive current makes it suitable for driving multiple loads or long traces without external buffers. Consider the 20-pin SOIC package constraints and thermal requirements during PCB layout design to ensure reliable operation across the industrial temperature range.

Part Context

This part belongs to the 74FCT logic family, designed for high-speed CMOS applications compatible with TTL inputs. It serves as a standard solution for parallel data latching in computer peripherals and communication interfaces. The IDT branding indicates its origin from Integrated Device Technology, now part of Renesas Electronics, maintaining legacy specifications for system upgrades.

Replacement Considerations

Direct substitutes include the 74FCT823ATSOCT and 74FCT823BTQ. Verify that replacement parts maintain identical pin configurations and electrical characteristics, particularly the master reset polarity and output drive strengths, before implementation.
