MK74CB218R

Clock Buffers, Drivers Overview

The MK74CB218R is a dual single-input to eight-output non-inverting clock driver manufactured by IDT (now Renesas). It operates at frequencies up to 200 MHz with output skew matched within 250 ps. The device supports 3.3 V or 2.5 V output voltages and features an Output Enable pin that tri-states each bank of eight outputs. Inputs can be connected together for a 1-to-16 fanout buffer configuration. It is packaged in a 28-pin SSOP.

Clock Buffers, Drivers Feature Summary

• Dual 1-to-8 low-skew clock drivers
• Output skew matched to within 250 ps
• Supports 2.5 V or 3.3 V output voltages
• Clock speeds up to 200 MHz

Clock Buffers, Drivers Applications

• Systems requiring part-to-part matching elimination
• Voltage translation between 3.3 V inputs and 2.5 V outputs
• High-speed clock distribution networks

Clock Buffers, Drivers Procurement Notes

Verify the component status as End-of-Life (EOL) for non-green parts occurred on May 13, 2010. Ensure procurement of RoHS-compliant versions if required, indicated by the 'LF' suffix in the ordering information.

Clock Buffers, Drivers Selection Notes

Select this component only for legacy designs; it is not recommended for new designs. For new applications, consult the manufacturer regarding the MK74CB218B as the designated replacement.

Clock Buffers, Drivers Part Context

The MK74CB218R belongs to the Buffalo™ family of clock drivers designed to interface with IDT clock synthesizer devices. The inputs are specifically matched to the outputs of these synthesizers to ensure signal integrity in high-speed systems.

Clock Buffers, Drivers Replacement Considerations

The datasheet explicitly recommends the MK74CB218B for new designs instead of the MK74CB218R.
