49FCT805PYGI8

Overview

The Renesas Electronics Corporation 49FCT805PYGI8 is a dual clock driver and distribution integrated circuit belonging to the 49FCT series. It features two independent driver banks, each providing a 1:5 fanout ratio with CMOS outputs. The device operates on a single 5V power supply and supports LVCMOS input logic levels. Designed for high-speed clock distribution applications requiring low skew and high signal quality, it utilizes advanced CMOS technology. The component is housed in a 20-pin SSOP package suitable for surface-mount assembly.

Feature Summary

• Dual 1:5 fanout clock driver architecture
• CMOS output drivers compatible with standard logic families
• LVCMOS input interface for direct connection to system controllers
• Single 5V power supply operation

Applications

• High-speed clock distribution networks
• Address bus distribution systems
• Point-to-point transmission line driving
• System timing synchronization circuits

Procurement Notes

Verify the specific suffix 'PYGI8' against official Renesas documentation to confirm pinout compatibility and electrical specifications relative to other 49FCT805 variants. Confirm current availability status as this part number may be subject to discontinuation or lifecycle changes. Ensure sourcing from authorized distributors to guarantee authenticity and traceability of the semiconductor components.

Selection Notes

Select this component when a dual-channel clock buffer with 1:5 fanout is required for 5V logic systems. The CMOS output type necessitates verification that downstream loads are compatible with CMOS voltage levels. Consider the 20-SSOP package dimensions for PCB layout constraints. Evaluate if the fixed 1:5 fanout meets the specific node count requirements of the design without excessive buffering.

Part Context

This component is part of the broader 49FCT family of high-speed clock drivers. Variants within this family differ by output type (CMOS vs TTL), package style (SSOP, SOIC, QSOP), and operating temperature ranges. The 49FCT805 specifically denotes the dual 1:5 configuration, distinguishing it from single-channel or different fanout ratios like the 49FCT3805.

Replacement Considerations

Direct replacements include other 49FCT805 variants with identical functionality but different packages or suffixes, such as 49FCT805APYG8 or 49FCT805CTSOG, provided the package footprint and output drive characteristics match the existing design requirements.
