Technical Details & Description

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.

No lead-time number to publish — every order is a fresh quote.

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.
