49FCT3805ASOGI

Overview

The Renesas 49FCT3805ASOGI is a dual 1-to-5 clock driver and fanout buffer built on advanced CMOS technology. It operates within a supply voltage range of 3V to 3.6V, typically for 3.3V systems. The device features two independent driver banks, each providing five outputs with individual output enable controls. Designed for high-speed clock distribution, it ensures low skew and high signal quality. The component is housed in a 20-pin SOIC package (0.295 inch width) and supports surface mount installation.

Feature Summary

• Dual 1:5 fanout architecture with independent output enable control for each bank
• Low capacitance inputs designed for high-speed clock distribution applications
• Integrated heartbeat monitor output for diagnostics and PLL driving support
• LVCMOS/LVTTL compatible input and output logic levels

Applications

• High-speed clock distribution networks requiring low skew
• Address distribution where signals must be sent to multiple receivers
• Single point-to-point transmission line driving
• System diagnostics via heartbeat monitoring

Part Context

This component belongs to the 49FCT series of clock drivers manufactured by Renesas Electronics. It is functionally equivalent to parts previously branded under IDT, such as the IDT49FCT3805ASOGI. The 'A' suffix typically denotes specific manufacturing revisions or enhanced specifications within the family, while 'SOGI' indicates the SOIC-20 package type.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical parameters against alternative dual 1:5 clock drivers if sourcing this discontinued or limited-stock item.
