Clock Buffers, Drivers Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life status updates. The product does not comply with RoHS standards. Buyers should confirm the specific suffix 'CTQ' corresponds to the required packaging and material specifications, as ordering suffixes may indicate variations in tape-and-reel quantities or lead frame materials.

Clock Buffers, Drivers Selection Notes

Select this part when a single clock source needs to drive five distinct loads with minimal skew. Ensure the design environment remains within the 0°C to 70°C commercial temperature range. Verify that the 100 MHz maximum frequency meets the system's timing requirements. The 20-SSOP footprint must be accommodated by the PCB layout. Note that this device provides non-differential outputs; differential signaling requirements necessitate alternative components from the FCT family.

Clock Buffers, Drivers Part Context

The IDT74FCT810CTQ is part of the broader 74FCT logic family produced by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. This specific model serves as a high-performance CMOS buffer designed to replace older TTL technologies while offering lower power consumption. The 'CTQ' suffix typically denotes a specific tape-and-reel packaging option for automated assembly, distinguishing it from tube-packaged variants like the 'BT' or 'DT' versions.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the device is discontinued, engineers must evaluate pin-compatible alternatives from the same 74FCT family or modern equivalents that support 1:5 fan-out and 100 MHz operation. Verify electrical parameters such as propagation delay and output drive strength against the original datasheet before substitution.
