Active production — BOM-fit for new designs
The 524SDCGI: As a 1:4 clock buffer accepting LVCMOS inputs and delivering LVCMOS outputs up to 200 MHz, it fits general-purpose clock-tree fanout where single-ended distribution is sufficient and differential pairs are not required.
The single-circuit, 1:4 fanout ratio means one input drives four output traces; the non-differential I/O (No/No) keeps PCB layout simple compared to a PECL or CML fanout buffer.
Cross-reference note
The 5PB1104PGGK is the closest parametric peer — same 1:4 ratio, same 200 MHz ceiling, same 8-SOIC package, and the same -40°C to 105°C temperature range. The 524SDCGI is a direct functional alternative for that BOM position without a board spin.
