Two independent buffers are packed into a single 20-SOIC, so one device can drive up to ten clock loads from two separate sources. The 3V to 3.6V supply range mates directly with 3.3V logic families common in telecom line cards, base station timing modules, and industrial controllers that need clean clock distribution without differential signalling. ## What the ratings mean for your BOM The 0°C to 70°C commercial temperature range limits this part to indoor, conditioned environments. It's fine for a lab instrument, a server motherboard, or a telecom rack in a climate-controlled room. Don't spec it for an outdoor radio head or an engine bay — that's where the industrial-temperature fanout buffers live. ## Lifecycle and sourcing reality The 49FCT3805SOG carries an Active lifecycle status with ROHS3 compliance. There's no NRND flag or last-time-buy notice on this line, so it's safe to freeze into a production BOM without worrying about an imminent EOL.","metaTitle":"49FCT3805SOG Fanout Buffer, 1:5, 20-SOIC, Active","metaDescription":"49FCT3805SOG is a 2-circuit fanout buffer with 1:5 ratio, CMOS/LVTTL I/O, 3V-3.6V supply, 0-70°C.
