74FCT807BTQG8

Overview

The 74FCT807BTQG8 is a clock driver and distribution component manufactured by Renesas Electronics. It functions as a 1:10 clock driver with TTL outputs, designed for high-speed signal distribution. The device operates within a supply voltage range of 4.75V to 5.25V and supports a maximum frequency of 100 MHz. It is housed in a 20-SSOP package (SSOP-20) suitable for surface mount technology. The component is classified under the 74FCT807T series and is currently marked as obsolete or end-of-life status.

Feature Summary

• 1:10 Clock Driver Configuration
• TTL Output Compatibility
• 100 MHz Maximum Frequency
• 20-SSOP Surface Mount Package

Applications

• Clock distribution networks
• Digital system timing circuits
• Bus-oriented applications requiring fan-out buffering

Procurement Notes

This component is identified as obsolete or end-of-life by the manufacturer. Availability is restricted, and it may not be sold in all regions through standard distributors like Mouser. Verification of current stock status and alternative sourcing channels is required before procurement planning.

Selection Notes

Select this part for applications requiring a single input to ten TTL-compatible outputs at frequencies up to 100 MHz. Ensure the design accommodates the 4.75V–5.25V supply requirement. Due to its obsolete status, consider evaluating newer equivalents from the same family or alternative manufacturers if long-term production support is necessary.

Part Context

The 74FCT807BTQG8 belongs to the 74FCT logic family, which offers CMOS power levels with true TTL compatibility. It provides high drive outputs (-15mA IOH, 48mA IOL) and low leakage currents. This specific variant uses the 'B' speed grade and 'TQG8' suffix indicating the SSOP-20 package and reel/cut-tape packaging format.

Replacement Considerations

Direct substitutes include other variants within the 74FCT807T series such as 74FCT807CTQG8 or 74FCT807BTQGI8, depending on package and speed requirements. Cross-reference with IDT74FCT807BTQG8 as an alias.
