74FCT3807AQG8

Overview

The Renesas Electronics 74FCT3807AQG8 is a single-input, ten-output clock buffer and distribution IC from the 74FCT series. It operates within a supply voltage range of 3 V to 3.6 V and supports maximum output frequencies up to 166 MHz. The device accepts TTL-compatible input signals and provides CMOS/TTL outputs. Packaged in a 20-pin QSOP (0.154 inch width) surface-mount format, it functions within an industrial temperature range of 0°C to +70°C with a typical operating current of 15.5 mA.

Feature Summary

• 1:10 fan-out ratio for clock signal distribution
• Maximum operating frequency of 166 MHz
• TTL input compatibility with CMOS/TTL outputs
• 20-lead QSOP surface-mount package

Applications

• Clock distribution networks in digital systems
• High-speed data acquisition equipment
• Telecommunications infrastructure timing circuits

Procurement Notes

Verify the specific suffix 'QG8' against the manufacturer's latest datasheet to confirm pinout and electrical characteristics match the design requirements. Confirm RoHS compliance status as indicated in official documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single clock source must drive ten distinct loads with TTL-level input compatibility. Ensure the system power supply remains strictly between 3 V and 3.6 V. Verify that the 20-QSOP footprint fits the PCB layout constraints and that the 0°C to +70°C operating range meets environmental conditions.

Part Context

This part belongs to the 74FCT3807 family of high-speed clock buffers. Variants such as 74FCT3807APYG8 differ primarily in packaging dimensions or temperature ratings. The 'A' suffix typically denotes specific manufacturing lot or revision details defined by Renesas.

Replacement Considerations

The 74FCT3807AQG is listed as a parameter-equivalent alternative by the manufacturer. Verify pin compatibility and electrical specs before substitution.
