IDT49FCT3805AQGI

The IDT49FCT3805AQGI is a 3.3V CMOS dual 1-to-5 clock driver/buffer from Renesas Electronics, part of the 49FCT3805/A family optimized for high-speed clock distribution. This device integrates two independent fanout buffers, each accepting a single input and driving five outputs with tightly controlled output-to-output skew and low propagation delay, ensuring synchronous clock delivery to multiple loads. The 3.3V CMOS core provides a favorable balance of speed and reduced power dissipation, while TTL-compatible inputs simplify interfacing with mixed logic environments. Packaged in a space-efficient Shrink Small Outline Package (SSOP), the device supports dense board layouts without sacrificing signal integrity or drive capability.

Typical end-use scenarios include clock fanout in enterprise networking switches, telecommunication base stations, RAID storage arrays, industrial automation controllers, and embedded computing backplanes where deterministic timing is essential. The QGI suffix designates an industrial temperature range of -40°C to +85°C, suiting deployment in harsh or thermally stressed environments. As a mature logic family from a legacy IDT portfolio now maintained by Renesas, procurement teams should confirm active lifecycle status and factor in potential long-term availability when specifying this part for new designs. This industrial-grade buffer does not carry military screening (/883) or extended temperature ratings; projects requiring full MIL-STD qualification should evaluate alternative suffix options or parallel-sourced equivalents. Authorized distribution channels are recommended to secure traceable, factory-original components and mitigate counterfeiting risks.
