49FCT805BTPYG

Overview

The Renesas Electronics Corporation 49FCT805BTPYG is a high-speed clock buffer and driver manufactured using 0.5-micron CMOS technology. It features two independent output banks, each providing a 1:5 fanout with three-state control. The device supports TTL-compatible inputs and outputs, delivering high drive capability of -32mA IOH and +48mA IOL. Key performance metrics include guaranteed low skew of less than 500ps maximum and very low duty cycle distortion under 600ps maximum. It includes a 'heartbeat' monitor output for diagnostics and PLL driving, ensuring signal integrity in high-speed clock distribution applications.
