200 MHz and the CMOS-only path
At 200 MHz this is not a high-speed LVPECL or LVDS fanout — those parts (like the 8SLVP2108) push 2 GHz and handle differential signals. The 553MILFT is strictly single-ended CMOS in and out, with no differential support. That is fine for the vast majority of board-level clock trees where the oscillator or MCU outputs a CMOS clock and you need to split it to a few peripherals. The 1:4 ratio is enough for a typical three-load fanout with one spare.
Active, in production, and easy to source
The part is ROHS3 compliant. For BOM planning, this is a straightforward line item — no PCN watch needed.
8-SOIC — a field-swappable package
The 8-SOIC package (0.154" body width, 3.90 mm) is one of the most common small-outline footprints. It is hand-solderable with a fine-tip iron and fits standard SOIC-8 land patterns. No hot-air station required for a field swap — just a steady hand and basic ESD kit. The part is surface-mount, so it sits flat on the board; orientation is marked by pin 1 identifier on the package.
