The 3 pF input capacitance keeps the load light on the driving source, and the 13 mA supply current at 3.3 V is typical for a single-channel LVDS fan-out buffer. ## 250 Mbps and 4.0 ns — timing budget for the serial link The 250 Mbps data rate is the ceiling for NRZ signalling through this buffer. At that rate the bit period is 4 ns, and the 4.0 ns propagation delay consumes nearly one full bit period of the timing budget — so cascading multiple SN65LVDS22DG4 stages in a single link is not practical without reducing the line rate. For a single fan-out stage driving a 50 cm backplane trace to two receivers, the 4.0 ns delay plus the output transition time still leaves enough setup-and-hold margin for most LVDS receivers rated at 250 Mbps. If the design needs to run at 400 Mbps or higher, this part is not the right choice; look at a dedicated LVDS repeater with sub-2 ns delay. The closest functional alternative is the SN65LVDS22 — the non-green/non-RoHS variant — but that part is also end-of-life. ## 16-SOIC footprint and 3.3 V rail No separate core or I/O supply — the single 3.3 V pin powers both the input receiver and the output drivers.","metaTitle":"TI SN65LVDS22DG4 LVDS Buffer Multiplexer, 250 Mbps, 16-SOIC","metaDescription":"Texas Instruments SN65LVDS22DG4 LVDS buffer and 1:2 multiplexer. 250 Mbps data rate, 4.0 ns delay, 3.3 V supply, -40°C to 85°C.","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":"Tube","Delay Time":"4.0ns","Applications":"-","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","Data Rate (Max)":"250Mbps","lifecycle_stage":"eol_hot","Current - Supply":"13mA","Voltage - Supply":"3V ~ 3.6V","Number of Channels":"1 x 2:2","Base Product Number":"SN65L","Capacitance - Input":"3 pF","Signal Conditioning":"-","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"16-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c6ca5b43b546fa4ced75c869b3a81f19.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65LVDS22DG4/alternatives.json"},"ai":{"faq":[{"question":"Is SN65LVDS22DG4 obsolete?","answer":"Yes, Texas Instruments lists the SN65LVDS22DG4 as Obsolete.
