49FCT3805BPYG

Overview

The 49FCT3805BPYG is a dual 1:5 non-inverting clock driver manufactured by Renesas Electronics. Built using advanced dual metal CMOS technology, it operates at a supply voltage of 3.3V. The device features two independent driver banks, each providing five outputs with individual output enable controls. It includes a 'heartbeat' monitor for diagnostics and PLL driving, where the MON output matches standard output specifications. Designed for high-speed clock distribution, it offers low capacitance inputs with hysteresis to ensure signal quality and minimal skew in critical applications.
