49FCT805CTPYG8

Overview

The Renesas Electronics Corporation 49FCT805CTPYG8 is a dual clock driver and distribution component belonging to the 49FCT series. It features two independent driver banks, each providing a 1:5 fanout ratio for clock signal distribution. The device utilizes CMOS technology with LVTTL-compatible inputs and outputs. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 20-SSOP package (0.209 inch width). The component is designed for high-speed clock buffering applications requiring low skew and high signal integrity.

Feature Summary

• Dual driver architecture with two independent 1:5 fanout buffers
• CMOS input/output logic levels compatible with LVTTL standards
• Operates on a single 4.5V to 5.5V power supply
• Available in a 20-pin SSOP surface-mount package

Applications

• High-speed clock distribution networks
• System timing synchronization circuits
• Digital logic interface buffering

Procurement Notes

This specific part number is identified as End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Procurement planning should account for potential discontinuation risks and lead time variability associated with legacy components.

Selection Notes

Designers selecting this component must verify compatibility with 5V logic systems due to its specific voltage requirements. The 20-SSOP package dimensions require adequate PCB footprint clearance. Since the device is discontinued, alternative solutions with similar pinouts and electrical characteristics should be evaluated for long-term production viability.

Part Context

The 49FCT805CTPYG8 is part of the broader 49FCT family of clock drivers produced by Renesas Electronics. This family focuses on high-performance clock distribution for digital systems. The 'CT' suffix typically denotes commercial temperature range specifications, while 'PYG8' indicates the specific SSOP package type and reel packaging configuration.

Replacement Considerations

Direct replacements are limited due to the EOL status. Engineers should evaluate other 49FCT series variants or modern equivalents from Renesas that offer 1:5 fanout capabilities in comparable packages. Cross-referencing datasheets for electrical parameters and pin configurations is essential before substitution.
