It operates from a 3V to 3.6V supply and comes in a 20-SSOP surface-mount package. This is a commercial-temperature-grade part (0°C to 70°C), suited for indoor equipment like servers, telecom line cards, and test instrumentation where a clean, non-differential clock fanout is needed. ## 1:10 fanout — BOM density per clock tree The 1:10 input-to-output ratio is the key density spec. One 74FCT3807APYG replaces two 1:4 or 1:5 buffers, saving board area and reducing the number of clock-tree stages. The non-differential topology (No/No for differential input/output) means it is a straight single-ended buffer — no PECL or CML translation needed, which simplifies the layout for 3.3V CMOS clock distribution. ## 3.3V supply rail — what it means for the power design The supply range is 3V to 3.6V, which is essentially a 3.3V ±10% rail. This buffer will not run from a 2.5V or 5V supply without a regulator. On a mixed-voltage board, allocate a dedicated 3.3V rail or a local LDO for this device to keep the clock buffer supply clean — switching noise on the supply rail couples into the output jitter. ## Commercial temperature grade — deployment boundary Rated for 0°C to 70°C, this part is limited to indoor, temperature-controlled environments. ## Active lifecycle — no end-of-life pressure ROHS3 compliance is confirmed.","metaTitle":"74FCT3807APYG Fanout Buffer, 1:10, 100 MHz, 20-SSOP","metaDescription":"74FCT3807APYG clock buffer from 74FCT series. 1:10 fanout, 100 MHz max, LVTTL input, CMOS/TTL output. 3V-3.6V supply, 20-SSOP, ROHS3.","metaKeywords":null},"attributes":{"series":"74FCT","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Clock & Timing ICs"],"specifications":{"Type":"Fanout Buffer (Distribution)","Input":"LVTTL","Output":"CMOS, TTL","Series":"74FCT","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","Frequency - Max":"100 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Number of Circuits":"1","Ratio - Input:Output":"1:10","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"20-SSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.54","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.54000","currency":"USD"},{"qty":10,"price":"$1.37600","currency":"USD"},{"qty":25,"price":"$1.30600","currency":"USD"},{"qty":100,"price":"$1.07270","currency":"USD"},{"qty":250,"price":"$1.00276","currency":"USD"},{"qty":500,"price":"$0.88616","currency":"USD"},{"qty":1000,"price":"$0.73480","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0891a1aaac541bfdcd74a9a630e27144.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum frequency of the 74FCT3807APYG?","answer":"The 74FCT3807APYG is rated for a maximum frequency of 100 MHz.
