49FCT3805BSOGI8

Overview

The 49FCT3805BSOGI8 is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and features two independent driver banks, each providing a 1:5 fanout ratio with individual output enable controls. The device utilizes CMOS or LVTTL input and output logic levels. It is housed in a 20-SOIC package (0.295 inch / 7.50mm width) designed for surface-mount installation. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual 1:5 clock driver architecture with independent output enable control per bank
• CMOS/LVTTL compatible inputs and outputs for flexible interface integration
• Low capacitance inputs with hysteresis to support high-speed signal integrity
• Integrated 'heartbeat' monitor output for diagnostics and PLL driving verification

Applications

• High-speed clock distribution systems requiring low skew
• Address distribution networks involving point-to-point transmission line driving
• Diagnostics monitoring via the dedicated heartbeat monitor output

Procurement Notes

Verify current availability status as this component may be subject to discontinuation notices. Confirm that the SOIC-20 package variant matches the specific design requirements. Ensure compliance with RoHS directives before procurement. Cross-reference the manufacturer part number against official Renesas documentation to validate authenticity and revision history.

Selection Notes

Select this component when a dual-bank clock distribution solution with 1:5 fanout is required within a 3.3V system environment. The inclusion of a heartbeat monitor makes it suitable for applications demanding diagnostic capabilities. Verify that the 20-SOIC footprint fits the PCB layout constraints and that the -40°C to +85°C industrial temperature range meets operational needs.

Part Context

This part belongs to the 49FCT series of FCT (Fast CMOS Technology) clock drivers. It shares functional similarities with variants like the 49FCT3805ASOGI8 and 49FCT3805BPYG, differing primarily in package type or minor electrical characteristics. The series is designed for high-performance clock buffering and distribution in digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Evaluate pin-compatible alternatives within the same 49FCT family or consult manufacturer documentation for direct replacements.
