49FCT805SOGI

Overview

The Renesas Electronics 49FCT805SOGI is a dual clock driver and distribution buffer belonging to the 49FCT805 series. It features two independent buffers, each providing a 1-to-5 fanout capability with CMOS outputs. The device operates on a single 5V supply voltage and utilizes an SOIC-20 surface-mount package. Designed for high-speed digital applications, it supports maximum output frequencies up to 166 MHz. The component is classified as End-of-Life (EOL) by the manufacturer.

Feature Summary

• Dual independent clock buffers with 1:5 fanout ratio per channel
• CMOS output logic levels compatible with standard CMOS loads
• Maximum operating frequency of 166 MHz
• Single 5V power supply operation

Applications

• High-speed clock distribution in data communication systems
• Buffering reference clocks for memory subsystems
• Clock tree generation in industrial control equipment

Procurement Notes

This component is officially discontinued and no longer manufactured by Renesas Electronics. Verification of availability is restricted to existing stock from third-party distributors or surplus markets. Buyers must confirm the authenticity of legacy inventory and check for relevant Product Change Notices (PCN) regarding manufacturing origin changes before procurement.

Selection Notes

Designers requiring this specific part number must evaluate alternative components due to its End-of-Life status. Selection should focus on devices offering identical 1:5 fanout ratios, CMOS outputs, and 166 MHz speed capabilities within a 20-pin SOIC package. Compatibility checks for pin configurations and electrical parameters are essential when transitioning to successor models.

Part Context

The 49FCT805SOGI is part of the broader 49FCT family of fast CMOS clock drivers. This series was widely used for buffering and distributing clock signals in high-performance digital circuits. The 'GI' suffix typically denotes the SOIC-20 package variant with industrial temperature range specifications, although specific thermal limits require datasheet confirmation.

Replacement Considerations

Public documentation identifies the 8L30210NLGI8 as a similar replacement option offered by Renesas Electronics Corporation.
