49FCT3805ASOGI8

Overview

The 49FCT3805ASOGI8 is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It operates within a supply voltage range of 3V to 3.6V and supports LVCMOS/LVTTL input and output logic levels. The device features two independent driver banks, each providing a 1:5 fanout ratio with individual output enable controls. Designed for high-speed clock distribution, it ensures low skew and high signal quality. The component is housed in a 20-SOIC package (0.295 inch width) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:5 fanout clock drivers with independent output enable control
• LVCMOS/LVTTL compatible inputs and outputs
• Low capacitance inputs for high-speed signal integrity
• Operates on 3V to 3.6V supply voltage

Applications

• High-speed clock distribution networks
• Address distribution systems requiring low skew
• Single point-to-point transmission line driving
• PLL driving applications

Procurement Notes

This component is listed as End-of-Life (EOL) or discontinued by the manufacturer. Availability is limited to existing stock or surplus markets. Verification of authenticity and storage conditions is critical due to the obsolescence status. Buyers should confirm the specific suffix 'ASOGI8' matches their design requirements, as pinouts and electrical characteristics may differ from active replacements.

Selection Notes

Select this part for designs requiring dual 1:5 clock buffering with LVCMOS/LVTTL compatibility. Ensure the PCB footprint accommodates the 20-SOIC package dimensions. Verify that the system power supply remains strictly within the 3V to 3.6V range to prevent malfunction. Consider the -40°C to +85°C industrial temperature rating when evaluating environmental constraints.

Part Context

The 49FCT3805A belongs to the FCT family of fast CMOS logic devices. The 'A' suffix typically denotes improved specifications or revisions compared to earlier versions. This specific part integrates diagnostic capabilities, including a heartbeat monitor output identical to other outputs, facilitating system health checks in complex digital architectures.

Replacement Considerations

Renesas recommends the 5PB1110PGGI8 as a replacement. Note that the 5PB1110 series may offer different voltage ranges (1.8V to 3.3V) and fanout ratios (up to 1:10). A full schematic review and timing analysis are required to ensure compatibility with the original 49FCT3805ASOGI8 design parameters.
