49FCT3805ASOG8

Overview

The Renesas 49FCT3805ASOG8 is a dual 1-to-5 clock driver and fanout buffer built using advanced CMOS technology. It operates on a single 3V to 3.6V supply voltage and features two independent driver banks, each with its own output enable control. The device supports CMOS and LVTTL input/output logic levels. 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 / 7.50mm width) and is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:5 fanout configuration with independent output enables
• Low capacitance inputs for high-speed performance
• Heartbeat monitor output for diagnostics and PLL driving
• CMOS/LVTTL compatible I/O levels

Applications

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

Procurement Notes

Verify the exact suffix against official documentation, as 'ASOGI8' and 'ASOG8' may denote different packaging or revision statuses. Confirm current availability status, as this series has been subject to discontinuance notifications. Ensure RoHS compliance details match specific manufacturing dates.

Selection Notes

Select this component when dual independent 1:5 clock buffering is required within a 3.3V system. Verify that the SOIC-20 package dimensions fit the PCB layout constraints. Ensure the input signal matches the specified CMOS or LVTTL voltage thresholds for proper logic level translation.
