49FCT805ASOG

Overview

The Renesas Electronics Corporation 49FCT805ASOG is a dual clock buffer and driver IC belonging to the 49FCT family. It features a 1:5 input-to-output ratio, distributing a single CMOS or LVTTL input signal to five outputs. The device operates on a 4.75V to 5.25V supply voltage and supports frequencies up to 166 MHz. It is housed in a 20-SOIC package with a width of 7.50mm. The component is designed for surface mount installation and functions within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Dual circuit configuration providing two independent 1:5 fan-out buffers
• Supports CMOS and LVTTL input/output logic levels
• Maximum operating frequency of 166 MHz
• Industrial temperature range operation from -40°C to 85°C

Applications

• Clock distribution networks in high-speed digital systems
• Buffering clock signals for FPGAs and ASICs
• Timing synchronization in telecommunications equipment

Procurement Notes

The 49FCT805ASOG is listed as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability requires checking authorized distributors for remaining stock or identifying qualified replacement components. Ensure any substitute part matches the original electrical specifications and pinout compatibility before integration into existing designs.

Selection Notes

Select this component when a dual-channel, 1:5 fan-out buffer is required for 5V CMOS or LVTTL applications. Verify that the 20-SOIC package dimensions fit the PCB layout constraints. Confirm that the 166 MHz maximum frequency meets the system timing requirements. Check if the industrial temperature range (-40°C to 85°C) aligns with the operational environment of the target application.

Part Context

This part belongs to the 49FCT series of fast CMOS clock drivers. It shares functional similarities with other variants like the 49FCT805CTSOG but differs in package type and temperature rating. The 'A' suffix typically denotes specific manufacturing or revision details within the Renesas product line. Understanding the broader 49FCT family helps in selecting alternative parts if this specific SOIC variant is unavailable.

Replacement Considerations

Publicly confirmed substitutes include the 8L30210NLGI from Renesas Electronics Corporation. When replacing, verify that the substitute maintains the 1:5 ratio, 5V operation, and compatible output drive strength. Ensure the new component's package and pinout are compatible or require adapter solutions.
