49FCT3805BPYGI8

Overview

The 49FCT3805BPYGI8 is a dual 1-to-5 clock driver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and features two independent driver banks, each providing five LVCMOS outputs with individual output enable controls. The device utilizes advanced CMOS technology for high-speed clock distribution with low input capacitance and hysteresis. It includes a dedicated 'heartbeat' monitor output identical to standard outputs for diagnostics and PLL driving. The component is housed in a 20-pin SSOP package and supports surface-mount installation.

Feature Summary

• Dual 1:5 fanout configuration with independent output enables
• Heartbeat monitor output for system diagnostics
• Low capacitance inputs with hysteresis
• LVCMOS compatible I/O levels

Applications

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

Part Context

This part belongs to the 49FCT series of FCT-compatible clock drivers. The 'B' suffix typically denotes specific electrical characteristics or revisions within the family, while 'PYG8' indicates the SSOP-20 package and tape-and-reel packaging. It serves as a buffer/driver solution for systems requiring signal integrity and precise timing distribution.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should verify pin compatibility and electrical specifications against alternative vendors such as Diodes Incorporated (e.g., PI49FCT32805QE) only after confirming datasheet alignment.
