49FCT805APYG

Overview

The Renesas Electronics Corporation 49FCT805APYG is a discontinued clock buffer and driver IC belonging to the 49FCT series. It functions as a dual fan-out buffer with a 1:5 input-to-output ratio, designed for CMOS and LVTTL signal compatibility. The device operates within a supply voltage range of 4.75V to 5.25V and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a 20-pin SSOP package (SSOP-20) with a width of 0.209 inches (5.30mm). The component utilizes surface-mount technology and complies with RoHS3 standards.

Feature Summary

• Dual circuit configuration providing two independent 1:5 fan-out buffers
• CMOS and LVTTL input/output logic levels compatible
• Industrial temperature rating spanning -40°C to +85°C
• RoHS3 compliant lead-free construction

Applications

• Clock distribution networks requiring signal buffering
• System timing architectures utilizing LVTTL interfaces
• Industrial control systems operating in extended temperature environments

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability should focus on identifying qualified replacement components or sourcing surplus inventory from authorized distributors. Procurement planning must account for the discontinuation status to ensure long-term supply chain stability.

Selection Notes

Designers selecting this component should verify that the 20-SSOP package dimensions align with the target PCB footprint. The 1:5 fan-out ratio and single-ended output structure define its capacity for driving downstream loads. Compatibility with 5V logic families and the specified voltage tolerance range are critical parameters for interface integration.

Part Context

The 49FCT805APYG is part of the broader 49FCT family of high-speed clock drivers. This series typically includes variants with different packaging options such as SOIC and QSOP, and varying temperature grades. The APYG suffix specifically denotes the SSOP package and industrial temperature range classification within this product line.

Replacement Considerations

Public records indicate the 8L30210NLGI as a potential substitute offered by Renesas Electronics Corporation. Designers should evaluate electrical parameter equivalence and pinout compatibility before implementing any cross-replacement.
