74FCT3807QGI

Overview

The 74FCT3807QGI is a single-input, ten-output clock driver manufactured by Renesas Electronics. Designed for high-speed digital systems, it operates within a supply voltage range of 3.0V to 3.6V and supports maximum frequencies up to 166 MHz. The device features LV TTL input compatibility and CMOS/TTL output drivers, housed in a 20-pin QSOP package with a width of 3.90mm. It functions as a fan-out buffer for clock distribution networks.

Feature Summary

• 1:10 Clock Distribution Ratio
• Maximum Frequency of 166 MHz
• LV TTL Input / CMOS TTL Output
• 20-Pin QSOP Package

Applications

• High-speed clock distribution networks
• Digital signal processing systems
• Communication equipment timing circuits

Procurement Notes

Verify component status prior to procurement as the 74FCT3807QGI is listed as discontinued. Confirm availability through authorized distributors or surplus channels. Ensure that the 20-SSOP/QSOP pinout matches the target PCB footprint. Review datasheet specifications for operating temperature ranges (-40°C to +85°C) and electrical characteristics to ensure system compatibility.

Selection Notes

Select this component for applications requiring a single source to drive ten loads at frequencies up to 166 MHz. Verify that the system operates within the 3.0V to 3.6V supply range. Consider alternative packages such as SSOP or TSSOP if different form factors are required, noting that suffixes may indicate package variations rather than functional changes.

Part Context

This part belongs to the 74FCT series of high-speed CMOS logic devices. It serves as a clock buffer and driver, distinct from lower-frequency variants like the 74FCT3807D (133 MHz max). The QGI suffix typically denotes the specific package type and tape/reel or tube packaging configuration used by Renesas.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, verify pin-to-pin compatibility with any potential cross-reference components before implementation.
