49FCT805CTSOG

Overview

The 49FCT805CTSOG is a dual clock driver and distribution component manufactured by Renesas Electronics. It operates within a 5 V supply voltage range and supports a maximum output frequency of 166 MHz. The device features a 1:5 multiplication factor, providing five outputs per input channel. Input signals are accepted via LVCMOS interfaces, while outputs support CMOS, LVCMOS, and TTL logic levels. Packaged in a 20-SOIC surface-mount format, the unit functions reliably between 0°C and +70°C with a typical operating current of 33.5 mA.

Feature Summary

• Dual-channel architecture with 1:5 fan-out ratio
• Maximum switching frequency of 166 MHz
• Mixed output compatibility including TTL, CMOS, and LVCMOS
• Standard 20-SOIC surface-mount package

Applications

• High-speed digital clock distribution networks
• TTL-compatible system timing circuits
• Multi-load clock buffering for bus architectures

Procurement Notes

This specific part number is listed as discontinued or end-of-life. Availability is restricted, and sourcing may require checking secondary market distributors or verifying alternative packaging options such as tape-and-reel variants like the 49FCT805CTSOG8. Verification of RoHS compliance and exact manufacturing origin is recommended prior to procurement due to potential lifecycle changes.

Selection Notes

Select this component when a dual-input, five-output buffer is required for systems utilizing mixed logic families. Ensure the design accommodates the 5 V nominal supply and 166 MHz speed limit. For automated assembly requirements, consider the reel-packaged equivalent if available, as the tube-packaged version may have limited stock.

Part Context

The 49FCT805CTSOG belongs to the 49FCT805T series of fast CMOS clock drivers. This family is designed for high-performance clock distribution in telecommunications and computing applications. The 'CTSOG' suffix denotes the specific SOIC-20 tube packaging variant within the broader product line.
