49FCT3805BSOG

Overview

The Renesas 49FCT3805BSOG is a 3.3V non-inverting clock driver built on advanced dual metal CMOS technology. It comprises two independent driver banks, each providing a 1:5 fanout with individual output enable controls. The device features low capacitance inputs with hysteresis and includes a 'heartbeat' monitor output for diagnostics and PLL driving. Designed for high-speed clock distribution where signal quality and skew are critical, it supports single point-to-point transmission line driving.

Feature Summary

• Dual 1:5 fanout clock drivers with independent output enables
• Low capacitance inputs with hysteresis for improved signal integrity
• Integrated heartbeat monitor output for diagnostics
• 3.3V supply voltage operation

Applications

• High-speed clock distribution systems
• Address distribution networks requiring low skew
• PLL driving applications
• Single point-to-point transmission line driving

Procurement Notes

Verify the specific suffix 'SOG' against official Renesas documentation to confirm package dimensions and tape/reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region.

Selection Notes

Select this component when dual independent 1:5 clock buffering is required at 3.3V. Ensure the application benefits from input hysteresis and requires a dedicated diagnostic monitor output. Verify that the SOIC-20 package fits the PCB layout constraints compared to SSOP alternatives.

Part Context

This part belongs to the 49FCT series of high-speed CMOS clock drivers. It shares functional similarities with variants like the 49FCT3805ASOGI8 and 49FCT3805APYGI8, differing primarily in package type (SOIC vs. SSOP) and specific manufacturing revisions indicated by the suffix.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other 49FCT3805 variants only if pin compatibility and electrical parameters match exactly.
