It handles clock rates up to 250 MHz, so it fits systems where a processor, FPGA, or SerDes needs to select among multiple reference clocks — say, a base frequency for normal operation and a lower-speed fallback for debug or power-save mode. The 12:1 ratio means you can park a dozen crystal oscillators or PLL outputs on the inputs and switch between them without external mux logic. ## Supply range and temperature — where it lives Supply voltage spans 2.375 V to 3.465 V. The industrial temperature range is -40°C to 85°C. ## Lifecycle and compliance — no surprises Renesas lists the 850S1201BGILFT as Active and ROHS3 compliant. No end-of-life notice, no last-time-buy clock ticking. You can drop it into a new BOM today and expect it to be there for the production run. ROHS3 means it meets the current exemption list — no special paperwork for EU-bound equipment.","metaTitle":"Renesas 850S1201BGILFT Clock Multiplexer, 12:1, 250 MHz","metaDescription":"Renesas 850S1201BGILFT is a 12:1 clock multiplexer with LVCMOS/LVTTL I/O, 250 MHz max frequency, industrial temp range -40°C to 85°C, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Multiplexer","Input":"LVCMOS, LVTTL","Output":"LVCMOS, LVTTL","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Frequency - Max":"250 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 3.465V","Number of Circuits":"1","Ratio - Input:Output":"12:1","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-TSSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.09","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.09000","currency":"USD"},{"qty":10,"price":"$10.19500","currency":"USD"},{"qty":25,"price":"$9.77240","currency":"USD"},{"qty":100,"price":"$8.61010","currency":"USD"},{"qty":250,"price":"$8.18756","currency":"USD"},{"qty":500,"price":"$7.65934","currency":"USD"},{"qty":1000,"price":"$7.02546","currency":"USD"},{"qty":3000,"price":"$6.76134","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/aa2c598e955f42dd9f0fcc59504c7ccf.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 850S1201BGILFT RoHS compliant?","answer":"Yes, it is ROHS3 compliant, meeting current EU RoHS exemption requirements."},{"question":"When sourcing 850S1201BGILFT, what is the closest functional second-source — 5PB1104CMGK/W?","answer":"The 5PB1104CMGK/W is a 1:4 clock buffer, not a 12:1 multiplexer.
