Product details

What this 1:10 fanout buffer does on your board

The Renesas 74FCT3807AQG is a single-circuit fanout buffer that takes one LVTTL clock or signal input and distributes it to ten CMOS/TTL outputs, each capable of running up to 100 MHz.

Why the 1:10 ratio and 100 MHz matter for your BOM

The 1:10 fanout means a single clock source can drive up to ten loads. The 100 MHz ceiling is the maximum toggle rate.

Package rework and board-fit notes

The 20-QSOP (0.154-inch body width, 3.90 mm) is a fine-pitch SSOP variant. The narrow body means it takes less board space than a wide SOIC, but the pad spacing is tight enough that a good flux and controlled reflow profile matter.

Frequently asked questions

Is 74FCT3807AQG compatible with 3.3V?

Yes, the 74FCT3807AQG operates from a 3V to 3.6V supply, which directly covers the 3.3V logic rail. The LVTTL input and CMOS/TTL outputs are 3.3V-compatible without any level shifting.

Does 74FCT3807AQG support differential inputs?

No, the 74FCT3807AQG has non-differential inputs and outputs (LVTTL in, CMOS/TTL out). For differential clock distribution (e.g., LVPECL, LVDS), consider a part like the 8SLVP1104ANLGI, which accepts differential signals and provides LVPECL outputs.

What is the equivalent or second-source for 74FCT3807AQG?

There is no direct pin-compatible second-source listed in the official records. The closest functional peer in the same fanout-buffer class is the 8SLVP1104ANLGI, but that part is differential (LVPECL) and operates at 2 GHz — a different performance tier and signal type. For a drop-in replacement, stick with the 74FCT3807AQG.
