Procurement Notes

This specific part number, 74FCT3807DQGI8, is listed as discontinued or end-of-life. Verification of availability should focus on remaining stock from authorized distributors or third-party suppliers. Buyers must confirm the actual condition of any available units, as standard production has ceased. Alternative sourcing strategies or redesigns may be necessary due to the discontinuation status indicated in public records.

Selection Notes

When selecting this component, verify that the QSOP-20 package dimensions match the target PCB footprint. Ensure the design accommodates the 3V to 3.6V supply voltage requirement and the 166 MHz maximum frequency capability. Confirm that the TTL input logic levels are compatible with the driving source. Due to the discontinued status, evaluate equivalent active parts from the same family or newer generations if long-term supply stability is required.

Part Context

The 74FCT3807 series belongs to Renesas' high-performance FCT (Fast CMOS Technology) line, designed for low power consumption and high-speed operation. This specific variant utilizes the 'D' suffix to denote the industrial temperature grade and 'QGI8' to specify the QSOP-20 package with tape-and-reel packaging. It serves as a buffer to drive multiple loads from a single clock source in complex digital systems.

Replacement Considerations

Public records indicate the 74FCT3807DQGI8 is discontinued. Potential replacements include other variants within the 74FCT3807 family such as the 74FCT3807APYGI8 or 74FCT3807AQG8, provided they meet the package and temperature requirements. Verify pin compatibility and electrical specifications before substituting.
