49FCT3805BQG

Overview

The Renesas 49FCT3805BQG is a dual 1:5 fanout clock buffer operating on a single 3.3V supply. It integrates two independent driver banks, each providing five outputs with individual output enable controls. The device utilizes advanced CMOS technology to support high-speed clock distribution with low input capacitance and hysteresis for signal integrity. A dedicated heartbeat monitor output facilitates diagnostics and PLL driving. It is housed in a 24-pin QSOP package and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual 1:5 fanout architecture with independent output enables
• Heartbeat monitor output for system diagnostics
• Low capacitance inputs with hysteresis
• Single 3.3V power supply operation

Applications

• High-speed clock distribution networks
• Address bus distribution requiring low skew
• PLL driving circuits
• Point-to-point transmission line driving

Part Context

This component belongs to the FCT3805 family of non-inverting clock drivers. It is designed for applications where signal quality and skew are critical, allowing one signal to be distributed to multiple receivers efficiently.

Replacement Considerations

Verify pin compatibility and electrical specifications against alternatives such as the IDT49FCT3805 series or other Renesas FCT3805 variants like the 49FCT3805APYGI8.
