The MK74CB218B 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 MK74CB218B 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 IDT for more details. The MK74CB218B 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.
