The 100115SC is a low skew clock driver from the 100K ECL series, designed to distribute a clock signal with minimal delay variation between outputs. It's a logic-level buffer that takes one input and fans it out to multiple outputs while keeping the propagation delay matched across all paths — critical in synchronous systems where clock edge alignment matters.
For a rework tech, that means the leads are bare and easy to inspect before placement. The package itself is a standard SOIC footprint, so it'll sit flat under a hot-air nozzle without needing a preheat plate.
