The 553MILFT is strictly single-ended CMOS in and out, with no differential support. That is fine for the vast majority of board-level clock trees where the oscillator or MCU outputs a CMOS clock and you need to split it to a few peripherals. The 1:4 ratio is enough for a typical three-load fanout with one spare. ## Active, in production, and easy to source The part is ROHS3 compliant. For BOM planning, this is a straightforward line item — no PCN watch needed. ## 8-SOIC — a field-swappable package The 8-SOIC package (0.154\" body width, 3.90 mm) is one of the most common small-outline footprints. It is hand-solderable with a fine-tip iron and fits standard SOIC-8 land patterns. No hot-air station required for a field swap — just a steady hand and basic ESD kit. The part is surface-mount, so it sits flat on the board; orientation is marked by pin 1 identifier on the package.","metaTitle":"553MILFT ClockBlocks™ Fanout Buffer, 1:4, 200 MHz, 8-SOIC","metaDescription":"553MILFT is an active ClockBlocks™ fanout buffer, 1:4 CMOS, 200 MHz max, 2.375V–5.25V supply, -40°C to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":"ClockBlocks™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"CMOS","Output":"CMOS","Series":"ClockBlocks™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Frequency - Max":"200 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.375V ~ 5.25V","Number of Circuits":"1","Ratio - Input:Output":"1:4","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.92092","stockQuantity":0,"priceTiers":[{"qty":3000,"price":"$1.92092","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5d4b9f6643af64f064481c43ca3ee157.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 553MILFT active or obsolete?","answer":"553MILFT is Active in production and ROHS3 compliant.
