Each buffer takes one CMOS or LVTTL input and drives five CMOS or LVTTL outputs, giving you a total of ten outputs from two inputs. The part is non-differential on both input and output sides, so it is a straight single-ended fanout tree for standard logic-level clocks or data strobes. ## 166 MHz ceiling and 2.5 V supply — what they mean for the clock tree The 166 MHz maximum frequency covers the vast majority of board-level clock distribution for FPGAs, MCUs, and Ethernet PHYs running at 100 MHz or below. If your design needs to fan out a 125 MHz reference or a 100 MHz system clock, this part has margin. The supply voltage range of 2.3 V to 2.7 V locks it into 2.5 V nominal rails — it will not run from 3.3 V or 1.8 V without a regulator. That narrow range is a deliberate fit for low-voltage 2.5 V logic families, and it keeps the output swing clean across the industrial temperature span of -40°C to 85°C. ## Active lifecycle — no last-time-buy pressure The 49FCT20805PYGI carries an active product status and is ROHS3 compliant. There is no NRND flag, no EOL notice, and no LTB window to manage.","metaTitle":"49FCT20805PYGI Fanout Buffer, 166 MHz, 1:5, 20-SSOP","metaDescription":"Renesas 49FCT20805PYGI fanout buffer (distribution), 166 MHz max, 1:5 ratio, 2.3V–2.7V supply, -40°C to 85°C, 20-SSOP.
