IDT74FCT810CTSO

Clock Buffers, Drivers Overview

The IDT74FCT810CTSO is a clock buffer and driver manufactured by Renesas Electronics Corporation, belonging to the 74FCT logic series. It functions as a fan-out buffer with a 1:5 input-to-output ratio, designed for distributing clock signals in high-speed digital systems. The device supports a maximum operating frequency of 100 MHz and operates on a single 5V supply voltage ranging from 4.75V to 5.25V. It features TTL-compatible inputs and outputs, ensuring compatibility with standard logic families. The component is housed in a 20-SOIC (0.295", 7.50mm width) surface-mount package and is rated for an industrial operating temperature range of 0°C to 70°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'CTSO' against official Renesas documentation to confirm pinout and electrical characteristics match the standard 74FCT810 family specifications. Confirm RoHS compliance status, as older FCT variants may not meet current environmental standards. Check for obsolescence notices or product change notifications (PCN) prior to procurement.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended clock signal requires splitting into five identical paths with minimal skew. Ensure the system power supply remains within the 4.75V to 5.25V range. Verify that the 20-SOIC footprint fits the PCB layout constraints and that the 0-70°C temperature rating meets the operational environment requirements.

Clock Buffers, Drivers Part Context

This part belongs to the IDT 74FCT (Fast CMOS TTL) family, which bridges the speed advantages of CMOS technology with the drive strength and compatibility of TTL logic. The 74FCT810 is a specific variant dedicated to clock buffering, offering higher performance than standard 74HC series devices while maintaining 5V operation.

Clock Buffers, Drivers Replacement Considerations

Direct replacements include other 74FCT810 variants from Renesas or compatible vendors such as Cypress or Texas Instruments, provided they share the same 1:5 ratio, 100MHz speed, and 20-SOIC package. Verify pin compatibility before substitution.
