Clock fanout for single-ended trees
The Renesas 74FCT3807ASOGI is a 1:10 fanout buffer from the 74FCT series, designed to distribute a single LVTTL clock input to ten CMOS or TTL outputs. It runs from a 3V to 3.6V supply rail and handles clock rates up to 100 MHz. The industrial temperature range (-40°C to 85°C) qualifies it for motor drives, telecom line cards, and factory automation controllers.
1:10 ratio and 100 MHz ceiling
The 1:10 input-to-output ratio means one clock source drives ten loads without needing a second buffer stage. At 100 MHz the part keeps edge rates clean for most single-ended clock trees — think FPGA configuration clocks, Ethernet PHY reference clocks, or synchronous ADC sample clocks. The non-differential I/O (No/No) rules out LVPECL or LVDS fanout; this is strictly for LVTTL/CMOS rails.
20-SOIC footprint, surface-mount assembly
Housed in a 20-SOIC package (7.50 mm width), the part reflows on standard lead-free profiles. The wide-body SOIC gives good thermal contact to the PCB copper pour — useful if the buffer sits near a hot FPGA or processor. Tube shipment is the default; if your pick-and-place line feeds from tape, confirm the reel option with your distributor before committing the BOM line.
Active, no LTB watch needed
Renesas lists the 74FCT3807ASOGI as Active with ROHS3 compliance. No last-time-buy notice, no end-of-life window to track. For a production BOM that needs a single-ended clock fanout at 3.3V, this part is a stable line item — no urgency to qualify a second source unless your risk policy demands dual sourcing for all active logic.
