It is a non-inverting, non-differential buffer — no PLL, no jitter attenuation, no divide or multiply. What goes in at the input comes out at each output, just fanned out and re-driven. Maximum frequency is 100 MHz, which suits it for clock distribution in 74FCT, ALVC, or AVC logic systems, FPGA configuration clocks, and general-purpose synchronous bus trees. The supply range is 3V to 3.6V, so it runs cleanly off a 3.3V rail without an extra regulator. Industrial temperature grade (-40°C to 85°C) covers most rack-mount telecom, industrial controller, and test-equipment environments. ## What the 1:10 ratio means for your clock tree The 1:10 ratio is the part's main selection parameter. One clock source — an oscillator, a PLL output, or a crystal-based clock generator — can feed up to ten loads without needing a second buffer stage. That saves board area and reduces the number of active devices in the clock distribution path. Each output is a standard CMOS/TTL driver, so it can drive typical FPGA clock inputs, synchronous SRAM clock pins, or logic-gate clock enables directly. The non-differential, single-ended nature means it is not intended for LVDS or LVPECL clock trees; those need a different buffer family. ## Package and footprint The 74FCT3807QGI is supplied in a 20-QSOP package (0.154-inch body width, 3.90 mm pitch). It is a surface-mount device, so it reflows with standard lead-free profiles. The QSOP footprint is smaller than a SOIC-20, which helps on dense boards. The supplier device package is listed as 20-QSOP, which matches the package / case field. The part ships in tube form; if you need Tape & Reel for automated assembly, check the ordering code suffix — the base QGI variant is tube. ## Lifecycle and sourcing It is ROHS3 compliant, so it meets current EU and global environmental requirements.","metaTitle":"74FCT3807QGI Fanout Buffer, 1:10, 100 MHz, 20-QSOP","metaDescription":"74FCT3807QGI clock buffer: 1:10 fanout, 100 MHz max, LVTTL input, CMOS/TTL output, 3V–3.6V supply, -40°C to 85°C, 20-QSOP.
