Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'B' against the target part number MK74CB218BRLFTR, as standard listings often refer to MK74CB218RLFTR. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as availability varies. Check for obsolescence notices, as previous variants like MK74CB218BRLF have been marked as discontinued in some databases.

Clock Buffers, Drivers Selection Notes

Select this component when a dual-channel 1:8 clock buffer is required for LVCMOS systems. Ensure the design accommodates the 3V to 3.6V supply constraint. Verify that the 200 MHz frequency limit meets the system's clock requirements. Consider the 28-QSOP package dimensions for PCB layout compatibility.

Clock Buffers, Drivers Part Context

This part belongs to the Renesas Buffalo™ series of high-performance clock drivers. The series is characterized by low skew and jitter performance suitable for demanding clock distribution applications. The 'MK' prefix typically denotes military-grade or enhanced reliability variants within the broader 74CB family.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include the MK74CB218RLFTR (standard commercial grade) and the MK74CB218BRLF (tube packaging). Cross-reference pinouts and electrical specifications carefully before substitution.
