74FCT3807QG

Overview

The Renesas Electronics Corporation 74FCT3807QG is a single-input, ten-output clock driver and distribution buffer designed for high-speed digital systems. Operating within a supply voltage range of 3 V to 3.6 V, this component supports maximum output frequencies up to 166 MHz. It features CMOS and TTL compatible outputs and draws a typical operating supply current of 15.5 mA. The device is housed in a 20-pin QSOP package with surface mount installation. It functions as a 1:10 multiplier/divider factor clock buffer, suitable for applications requiring reliable signal distribution across multiple loads.

Feature Summary

• Single input to ten output configuration (1:10 ratio)
• Maximum operating frequency of 166 MHz
• CMOS and TTL output compatibility
• Supply voltage range of 3 V to 3.6 V

Applications

• Clock distribution networks in high-speed data acquisition systems
• Buffering clock signals for multiple synchronous logic components
• Signal distribution in telecommunications equipment
• Industrial control systems requiring precise timing alignment

Procurement Notes

Verify the specific suffix 'QG' against the manufacturer's latest datasheet to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status through official documentation before integration. Check for any recent Product Change Notices (PCN) that may affect assembly or sourcing parameters. Ensure the supplier provides traceable origin information consistent with Renesas Electronics standards.

Selection Notes

Select the 74FCT3807QG when a 1:10 fan-out capability is required with CMOS/TTL output levels. Compare the 166 MHz maximum frequency against system timing requirements. Consider the 20-QSOP package constraints for PCB layout. Evaluate power consumption at 15.5 mA against available thermal management solutions. Verify input signal compatibility with LVTTL or standard TTL sources.

Part Context

This component belongs to the 74FCT3807 series of clock drivers manufactured by Renesas Electronics. It serves as a specialized buffer for distributing a single clock source to ten separate destinations. The part is distinct from other variants like the 74FCT3807AQG8 which may have different packaging or temperature ranges. It replaces older generations such as the discontinued 74FCT3807EPYG in modern designs.

Replacement Considerations

The 74FCT3807AQG is listed as a parameter-equivalent alternative by distributors. Verify electrical specifications and package compatibility before substitution. Other family members like the 74FCT3807APYGI8 offer similar functionality but differ in operating temperature ranges and packaging types.
