Part Context

This component belongs to the 853S011BI series of clock buffers. It is functionally equivalent to other variants in the family such as the 853S011BMILFT and 853S011CGILF, differing primarily in package type (SOIC-8 vs TSSOP-8) and specific electrical tolerances defined by the suffix codes. The device represents a standard solution for buffering differential clock signals in legacy and modern high-speed designs.

Replacement Considerations

Public confirmed substitute part numbers include MC10EP89DG from onsemi. Designers should verify pin compatibility and electrical specifications against the original datasheet when considering alternative sources.
