MK74CB218BRLF

Clock Buffers, Drivers Overview

The MK74CB218BRLF is a dual 1-to-8 Buffalo clock driver manufactured by Renesas Electronics. It operates within a supply voltage range of 3 V to 3.6 V and supports maximum output frequencies up to 200 MHz. The device features CMOS and TTL compatible outputs and is housed in a QSOP-28 package with surface mount installation. Designed for the 74CB series, it functions as a clock distribution component with two independent circuits, each providing an 1:8 fan-out ratio. The operational temperature range extends from 0°C to +70°C.
