MK74CB218RLF

Clock Buffers, Drivers Overview

The MK74CB218RLF is a Buffalo™ clock fan-out buffer manufactured by Renesas Electronics. It features two independent circuits, each providing a 1-to-8 output ratio from a single LVCMOS input. The device supports maximum operating frequencies up to 200 MHz and operates on a supply voltage range of 3V to 3.6V. Designed for surface-mount assembly, it is housed in a 28-pin SSOP package with a width of 3.90mm. The component functions within an industrial temperature range of 0°C to 70°C.

Clock Buffers, Drivers Feature Summary

• Dual independent 1:8 clock distribution buffers
• Maximum frequency operation of 200 MHz
• LVCMOS input and output logic levels
• Supply voltage range of 3V to 3.6V

Clock Buffers, Drivers Applications

• Clock signal distribution in digital systems
• Fan-out buffering for high-speed logic interfaces
• Timing reference distribution in embedded hardware

Clock Buffers, Drivers Procurement Notes

The MK74CB218RLF is identified as an End-of-Life (EOL) product with discontinuance notifications available. Distribution availability is restricted or unavailable through major channels such as Mouser. Verification of current stock status and alternative sourcing strategies is required before procurement planning.

Clock Buffers, Drivers Selection Notes

Designers should verify the 200 MHz frequency limit against system timing requirements. The 3V to 3.6V supply constraint must be accommodated in the power architecture. Since the device is discontinued, long-term production viability requires evaluating replacement components that match the 28-SSOP footprint and electrical specifications.

Clock Buffers, Drivers Part Context

This component belongs to the 74CB Buffalo™ series of clock drivers. It serves as a legacy solution for distributing clock signals in systems requiring moderate fan-out capabilities. The part number suffix 'RLF' typically denotes specific packaging or tape-and-reel configurations within the broader MK74CB218 family.

Clock Buffers, Drivers Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source data. Engineers must identify cross-compatible devices based on pinout compatibility, electrical parameters, and package dimensions due to the EOL status.
