The driver's typical differential output swing of 350 mV into a 100 Ω termination is LVDS-standard, so any standard LVDS receiver on the far end will capture the data cleanly as long as the total jitter budget (driver + interconnect + receiver) stays under about 0.25 UI. For a 400 Mbps link that translates to roughly 625 ps of peak-to-peak jitter tolerance — achievable with a well-routed differential pair and a solid ground reference plane. The 3.0 V minimum supply means the driver still meets its output levels even if the 3.3 V rail droops under load, which is common in distributed power architectures. ## 8-HVSSOP with PowerPad — thermal and layout notes Without the via stitch, thermal resistance rises significantly and the device may hit thermal shutdown above 85°C ambient. The exposed pad also provides a low-inductance return path for the high-frequency output currents, which helps control radiated emissions. The package footprint is 3.00 mm × 3.00 mm (0.118\" × 0.118\"), matching the standard 8-MSOP land pattern with the centre pad added. TI lists the SN65LVDS9638DGN as Active. For dual-sourcing or second-source qualification, the 65LVDS family includes the SN65LVDS9638D (the same die in a standard 8-SOIC package) — the DGN variant is the smaller HVSSOP footprint with the exposed pad, not a functional alternative. If your board already routes to the 8-HVSSOP land pattern, stick with the DGN suffix.","metaTitle":"TI SN65LVDS9638DGN LVDS Driver, 400 Mbps, 8-HVSSOP","metaDescription":"Texas Instruments SN65LVDS9638DGN is a dual LVDS driver rated at 400 Mbps per channel.","metaKeywords":null},"attributes":{"series":"65LVDS","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Driver","Duplex":"-","Series":"65LVDS","Package":"Tube","Protocol":"LVDS","Data Rate":"400Mbps","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"65LVDS9638","Operating Temperature":"-40°C~85°C","Supplier Device Package":"8-HVSSOP","Number of Drivers/Receivers":"2/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1400","priceTiers":[{"qty":1,"price":"$3.14000","currency":"USD"},{"qty":10,"price":"$2.82300","currency":"USD"},{"qty":25,"price":"$2.66880","currency":"USD"},{"qty":100,"price":"$2.31300","currency":"USD"},{"qty":250,"price":"$2.19436","currency":"USD"},{"qty":500,"price":"$1.96900","currency":"USD"},{"qty":1000,"price":"$1.67850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2fc8df5c44369a95af748012a35030ec.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/SN65LVDS9638DGN/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between SN65LVDS9638DGN and SN65LVDS9638D?","answer":"The difference is the package: the DGN variant uses the 8-HVSSOP with an exposed thermal pad (PowerPad), while the D variant uses a standard 8-SOIC without an exposed pad.
