IDT49FCT805ASO

Clock Buffers, Drivers Overview

The IDT49FCT805ASO is a non-inverting buffer and clock driver manufactured by Renesas Electronics Corporation, utilizing advanced dual metal CMOS technology. It features two independent output banks, each providing a 1:5 fanout from a standard TTL-compatible input. The device includes a 'heartbeat' monitor output for diagnostics and PLL driving. Electrical specifications include guaranteed low skew of less than 700ps maximum and low duty cycle distortion under 1ns. It operates with rail-to-rail output voltage swing and high drive capabilities of -24mA IOH and +64mA IOL.
