PRELIMINARY INFORMATION
MK74CB218
Dual 1 to 8 Buffalo™ Clock Driver
Description
Features
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.
• 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
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.
