If your controller or UART outputs 5V logic, you will need level translation on the driver inputs — the datasheet's input thresholds are referenced to the 3.3V rail. For 3.3V logic systems, this driver connects directly with no extra parts. The 4/0 driver/receiver count tells you this is strictly for the transmit leg of a differential bus; pair it with a separate RS485 receiver (like the AM26LV32) for a full interface. ## Package and footprint realities Surface-mount only — no through-hole variant in this order code. No exposed thermal pad on this package, so thermal dissipation goes through the leads; keep the ambient below 85°C if you are driving all four channels near their maximum output current.","metaTitle":"AM26LV31EIDR RS422/RS485 Driver, 3V-3.6V, 16-SOIC","metaDescription":"Texas Instruments AM26LV31EIDR quad RS422/RS485 line driver in 16-SOIC. 3V-3.6V supply, -40°C to 85°C.

The standard 5V AM26LV31 (non-E version) is pin-compatible but runs on a 5V supply. If your design is 3.3V-only, stick with the EIDR variant to avoid level-shifting the supply rail."},{"question":"Is AM26LV31EIDR compatible with 5V logic?","answer":"Not directly on the inputs. Driving it with 5V logic without level translation risks exceeding the input voltage range. Use a 3.3V-tolerant UART or add a level shifter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/AM26LV31EIDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/AM26LV31EIDR when reusing this data.
