49FCT805ASOGI

Overview

The Renesas 49FCT805ASOGI is a dual clock buffer and driver belonging to the 49FCT series. It features a 1:5 input-to-output ratio with two independent circuits, each providing one input and five outputs. The device operates on a single 4.75V to 5.25V supply voltage and supports CMOS and LVTTL input/output logic levels. Packaged in a 20-SOIC (0.295", 7.50mm wide) surface-mount housing, it is designed for high-speed clock distribution applications within an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual circuit configuration with 1:5 fan-out ratio per channel
• Supports CMOS and LVTTL input and output logic levels
• Operates on a 4.75V to 5.25V single power supply
• Available in a 20-SOIC surface-mount package

Applications

• High-speed clock distribution networks
• System timing and synchronization circuits
• Digital signal processing equipment clocking

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics Corporation. Verification of current availability should rely on distributor inventory status rather than manufacturer production lines. Buyers must confirm end-of-life documentation and ensure that any sourced units are genuine through authorized channels, as standard procurement channels may not stock new production.

Selection Notes

When selecting this part, verify compatibility with the system's voltage requirements, specifically the 4.75V to 5.25V range. Ensure the PCB footprint matches the 20-SOIC package dimensions. Since the device is obsolete, engineers should evaluate alternative components from the same family or newer generations that offer equivalent pinouts and electrical specifications to maintain design continuity.

Part Context

The 49FCT805ASOGI is part of the broader 49FCT805A product line, which includes variants with different packaging options such as SSOP and QSOP. The 'SOGI' suffix denotes the specific SOIC tube packaging. This series is designed for fast CMOS technology applications requiring low skew and high drive capability for clock signals in digital systems.

Replacement Considerations

Publicly documented substitutes include the 8L30210NLGI from Renesas Electronics Corporation. Users should compare pin configurations and electrical parameters before substitution.
