The 5 pF input capacitance and 46 mA supply current are typical for this class of fanout buffer. It comes in a 38-pin TSSOP package for surface-mount assembly. The 1:8 fanout saves board space versus discrete buffers, but the 38-TSSOP footprint is larger than a simple 1:4 buffer in a smaller package. The 400 Mbps ceiling means it handles 100BASE-TX, SGMII, or standard-definition video links, but not Gigabit Ethernet or 10 GbE serial lanes — those need a higher-rate redriver or retimer. No official successor part number appears in the available records. New designs should avoid this part and select an active LVDS fanout buffer — TI's SN65LVDS108 or SN65LVDS104/105 families are functionally similar but differ in fanout ratio and package, so a pin-to-pin drop-in replacement is not guaranteed without a layout review.","metaTitle":"SN65LVDS109DBTR LVDS Buffer/Multiplexer, 400 Mbps, Obsolete","metaDescription":"TI SN65LVDS109DBTR is a 1:8 LVDS buffer/multiplexer with 400 Mbps data rate, 2.8 ns delay, 3.3 V supply, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Buffer, Multiplexer","Input":"LVDS","Output":"LVDS","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Delay Time":"2.8ns","Applications":"-","Mounting Type":"Surface Mount","Package / Case":"38-TFSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Data Rate (Max)":"400Mbps","lifecycle_stage":"eol_hot","Current - Supply":"46mA","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"1 x 2:8","Base Product Number":"SN65L","Capacitance - Input":"5 pF","Signal Conditioning":"-","Operating Temperature":"-40°C~85°C","Supplier Device Package":"38-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/896da4cbff2c05a1cc597b9437ac793e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65LVDS109DBTR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for SN65LVDS109DBTR?","answer":"No official replacement part number is recorded. Functionally similar LVDS fanout buffers from TI include the SN65LVDS108 (1:8) and SN65LVDS104/105 (1:4) families, but these differ in pinout and package, so a board redesign is required.
