49FCT805BTSOG

Overview

The 49FCT805BTSOG is a dual clock driver and distribution component manufactured by Renesas Electronics. It operates with a multiplication/division factor of 1:5, supporting a maximum output frequency of 166 MHz. The device accepts LVCMOS inputs and provides CMOS, LVCMOS, and TTL outputs. It functions within a supply voltage range of 5 V and operates at temperatures between 0°C and +70°C. Packaged in an SOIC-20 format for surface mount installation, the unit draws a working power current of 33.5 mA.

Feature Summary

• Dual clock driver architecture with 1:5 multiplication/division ratio
• Maximum operating frequency of 166 MHz
• Supports CMOS, LVCMOS, and TTL output types
• Operates on a single 5 V supply voltage

Applications

• Clock signal distribution in digital systems
• TTL logic interface buffering
• High-speed data transmission timing circuits

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and distributors may not stock this item in all regions. Verification of current lifecycle status and alternative sourcing options is required before procurement planning.

Selection Notes

Select this part when a dual-channel clock buffer with mixed output compatibility (CMOS/LVCMOS/TTL) is needed. Ensure the design environment supports a 5 V supply and industrial temperature range of 0°C to +70°C. Verify that the 166 MHz frequency limit meets system timing requirements.

Part Context

The 49FCT805BTSOG belongs to the 49FCT805T series of Fast CMOS clock drivers. It shares functional similarities with other variants like the 49FCT805SOG but differs in specific package or suffix configurations. It serves as a legacy solution for high-speed clock distribution in older hardware designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineering teams should evaluate newer Renesas timing products or cross-reference with compatible buffer families.
