It is not a 5V-tolerant part; feeding it 5V on VCC exceeds the absolute maximum and will damage the device. If your existing RS-485 bus runs on a 5V rail, this driver needs its own 3.3V regulator or a level-shifting stage on the bus side. The part is a straight drop-in for 3.3V-only designs — quad drivers in the familiar 16-SOIC footprint, no external bias resistors needed for the driver outputs. Watch the common-mode voltage range on the differential outputs: at 3.3V supply the driver output swing is typically 2V differential into a 100Ω load, which meets RS-422/RS-485 signal levels for short-to-medium cable runs. For a BOM planner this means standard procurement lead times through distribution, no urgency to stockpile, and no redesign pressure from obsolescence. It is the right choice for benchtop instruments, server backplanes, office networking switches, and any equipment that lives in a climate-controlled space.","metaTitle":"TI AM26LV31CDRG4 RS-422/RS-485 Driver, 3V-3.6V, 16-SOIC","metaDescription":"Texas Instruments AM26LV31CDRG4 is a quad RS-422/RS-485 line driver in 16-SOIC. 3V to 3.6V supply, commercial temp 0°C to 70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Type":"Driver","Duplex":"-","Series":"-","Protocol":"RS422, RS485","Data Rate":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Part Status":"Last Time Buy","Manufacturer":"Texas Instruments","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"AM26LV31","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"16-SOIC","Number of Drivers/Receivers":"4/0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7f52f3dccbed78fa9a5323f00c54492f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/AM26LV31CDRG4/alternatives.json"},"ai":{"faq":[{"question":"Can AM26LV31CDRG4 work with a 5V supply?","answer":"No. The AM26LV31CDRG4 is specified for a supply voltage range of 3V to 3.6V. Applying 5V to the VCC pin exceeds the device's absolute maximum rating and will cause permanent damage.
