IDT74FCT3807SOGI

The IDT74FCT3807SOGI is a 3.3V CMOS 1-to-10 clock driver manufactured by Renesas Electronics, part of the legacy IDT 74FCT3807 family. This device accepts a single-ended clock input and distributes it to ten low-skew outputs, making it a fundamental building block for synchronous digital systems. The inputs are TTL-compatible, permitting direct interface with 5V or 3.3V logic families without level translation, while the CMOS outputs deliver rail-to-rail swing with high drive capability. Fabricated in a fast CMOS process, the driver exhibits low propagation delay and tight output-to-output skew—typically well under 500 ps—which preserves timing margins across multiple load points. Packaged in a narrow-body SOP-20 (SOIC) with the industrial temperature suffix “I,” it operates reliably from –40°C to +85°C, and the “G” suffix confirms RoHS-compliant, lead-free construction.

Typical applications include clock distribution in networking switches, telecommunications line cards, server backplanes, and high-reliability industrial control systems. In these environments, the driver is often used to fan out a single system oscillator to multiple FPGAs, ASICs, or memory banks, maintaining synchronization with minimal additive jitter. Procurement engineers should note that the IDT prefix reflects the original manufacturer before Renesas’ acquisition of IDT; the part remains an active, widely sourced product through authorized distribution. However, for programs with extended production lives—such as aerospace or defense platforms—verifying Renesas’ product lifecycle roadmap is a standard practice, as the commercial/industrial grade of this device does not carry a military screening level and may be subject to earlier obsolescence than dedicated high-reliability equivalents. Ensuring correct temperature grade and pack type against the specific bill of materials is critical during sourcing.
