49FCT805BTPYG8

Overview

The Renesas 49FCT805BTPYG8 is a high-speed clock fanout buffer and distribution IC from the 49FCT series. It utilizes advanced dual metal CMOS technology to provide non-inverting signal buffering. The device features two independent driver banks, each capable of driving five outputs, resulting in a total of ten outputs with a 1:5 split ratio per bank. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to +70°C. The component is housed in a 20-SSOP package (0.209 inch width) and is supplied in tape and reel format for surface-mount assembly.

Feature Summary

• Dual independent driver banks providing flexible clock distribution capabilities
• Advanced dual metal CMOS construction for high-speed performance
• Non-inverting logic function ensuring signal integrity preservation

Applications

• High-frequency clock distribution networks
• System timing synchronization circuits
• Data bus interface buffering

Procurement Notes

Verify the specific suffix 'BTPYG8' against official Renesas documentation to confirm package dimensions and tape specifications. Confirm end-of-life status and last-time-buy dates through authorized distributors. Ensure compatibility with existing PCB footprints for the 20-SSOP form factor before procurement.

Selection Notes

Select this component when dual-channel clock distribution with ten total outputs is required. The 1:5 ratio per bank suits applications needing symmetric signal splitting. Verify that the SSOP package fits the available board space and that the 4.5V to 5.5V supply range aligns with the system power architecture.

Part Context

This part belongs to the 49FCT family of fast CMOS buffers. These components are designed for high-performance digital systems requiring precise timing. The 49FCT805 variant specifically addresses multi-drop clock distribution needs, offering lower propagation delay compared to standard logic families.

Replacement Considerations

Check for direct pin-compatible alternatives within the 49FCT series. Consider variants with different output drive strengths or packaging options if the current stock is unavailable. Verify electrical parameter equivalence for any substitute parts.
