Product details

1:5 fanout buffer for single-ended clock trees

The Renesas 49FCT3805AQGI is a 1:5 fanout buffer for clock distribution — it takes a single CMOS or LVTTL input and drives five identical outputs. It runs on a 3V to 3.6V supply, so it sits cleanly on a 3.3V rail. The two internal circuits each provide a 1:5 fanout, giving you ten total outputs from two inputs if you use both halves. Inputs and outputs are single-ended only — no differential support, so this part is for LVCMOS or LVTTL clock trees, not LVPECL or LVDS lines. It is not rated for extended automotive under-hood environments, but it will work in cabin or chassis domains if the system's ambient stays within that range.

Frequently asked questions

Is 49FCT3805AQGI compatible with 3.3V?

Yes, the supply range is 3V to 3.6V, so a 3.3V rail is right in the middle. Inputs and outputs are CMOS and LVTTL levels, which are 3.3V-compatible.
