The maximum frequency of 166 MHz sets the upper bound for the clock tree — above that, output edge rates degrade and the jitter budget tightens. The 2.3V to 2.7V supply rail means this part lives on a dedicated low-voltage plane, not a shared 3.3V or 5V bus. ## Supply rail and temperature envelope Operating from 2.3V to 2.7V, the buffer is a fit for 2.5V nominal clock domains common in networking ASICs and FPGAs. ## Package and footprint The 1:10 fanout ratio means ten output traces must be length-matched to within the skew tolerance of the downstream loads — the SSOP pitch keeps the fan-out region compact enough for a single via per trace.","metaTitle":"74FCT20807PYGI Renesas 1:10 LVTTL Fanout Buffer 166 MHz","metaDescription":"74FCT20807PYGI Renesas 74FCT series fanout buffer, 1:10 ratio, 166 MHz max, LVTTL I/O, 2.3V-2.7V supply, -40°C to 85°C, 20-SSOP.","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":"LVTTL","Series":"74FCT","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"20-SSOP (0.209\\\", 5.30mm Width)","Frequency - Max":"166 MHz","lifecycle_stage":"eol_hot","Voltage - Supply":"2.3V ~ 2.7V","Number of Circuits":"1","Ratio - Input:Output":"1:10","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"20-SSOP","Differential - Input:Output":"No/No"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.03000","currency":"USD"},{"qty":10,"price":"$4.51900","currency":"USD"},{"qty":25,"price":"$4.27240","currency":"USD"},{"qty":100,"price":"$3.70270","currency":"USD"},{"qty":250,"price":"$3.51280","currency":"USD"},{"qty":500,"price":"$3.15200","currency":"USD"},{"qty":1000,"price":"$2.65832","currency":"USD"},{"qty":2500,"price":"$2.52540","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7cc02ca5bc40e9b00f95735be7cd6c96.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/74FCT20807PYGI","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/74FCT20807PYGI when reusing this data.
