The Renesas 74FCT3807SNDGI is a single-ended fanout buffer that takes one LVTTL input and distributes it to ten CMOS/TTL outputs at up to 200 MHz.
The non-differential I/O (No/No) means it is built for single-ended LVTTL/CMOS distribution, not LVPECL or LVDS clock trees — match the logic family before routing.
The SOIC variant uses a larger body and different footprint. The 74FCT3807SNDGI is a 20-VFQFN (3x3 mm) with exposed pad — verify the PCB land pattern and thermal pad connection before substituting. Electrical specs (200 MHz, 1:10, LVTTL in, CMOS/TTL out) are the same.
Both are 20-pin QFN packages from the same 74FCT3807 family with identical electrical ratings. The suffix difference typically indicates packing or tape/reel variation — the SNDGI ships in a tray, while the DGI may ship in tape and reel.
