This is a pure low-voltage driver — it does not run from a 5V rail. If your system uses 5V logic, you will need a level shifter or a 5V-tolerant RS-485 driver.
No exposed thermal pad, so no risk of tombstoning or pad lifting under the part. Will it survive the hot air? Yes — the plastic body handles reflow profiles without issue, and the leads are robust enough for a few rework cycles.
No LTB risk to flag for multi-year production runs.
It is designed for 3V to 3.6V supply only. It operates with 3.3V logic natively. For 5V logic systems, you will need a level translator or a different driver rated for 5V supply.
Within the same family, the AM26LV31C (base part number AM26LV31) shares the same quad-driver function and 3.3V supply. The primary difference is the temperature grade and package suffix. For a 5V supply alternative, consider the AM26C31 series.
