MK74CB218

PRELIMINARY INFORMATION MK74CB218 Dual 1 to 8 Buffalo™ Clock Driver Features Tiny 28 pin SSOP (150 mil) package Dual one input to eight output clock drivers Outputs are skew matched to within 250 ps A outputs and B outputs matched to 250 ps 2.5 V, 3.3 V or 5 V supply voltages Output Enable tri-states each bank of eight Clock speeds up to 200 MHz Description The MK74CB218 Buffalo™ is a monolithic CMOS high speed clock driver. It consists of two identical single input to eight low-skew output, non-inverting clock drivers. This eliminates concerns of part to part matching in many systems. The MK74CB218 is packaged in the tiny 28 pin SSOP, which uses the same board space as the narrow 16 pin SOIC. The inputs can be connected together for a 1 to 16 fanout buffer. A quad 1 to 4, and PECL versions, are also available. Consult ICS for more details. The MK74CB218 can also act as a voltage translator, since it is possible to run the inputs at 3.3 V and the outputs at 2.5 V. Family of ICS Parts The MK74CB218 Buffalo™ is designed to be used with ICS’s clock synthesizer devices. The inputs of the Buffalo are matched to the outputs of ICS clock synthesizers. Consult ICS for applications support.
