DescriptionDUAL 1 TO 8 BUFFALO CLOCK
The MK74CB218R 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 can eliminate concerns of part to part matching in many systems. The MK74CB218R 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.
The MK74CB218R 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.
A quad 1 to 4, and PECL versions, are also available. Consult IDT for more details.
Family of PartsThe MK74CB218R Buffalo? is designed to be used with IDT's clock synthesizer devices. The inputs of the Buffalo? are matched to the outputs of IDT clock synthesizers.
Not recommended for new designs. See the MK74CB218R for new designs.
