The AM26LV31EIDRG4: It packs four drivers into a single 16-SOIC package, with no receivers on-chip — this is a pure transmitter side for balanced data transmission over twisted-pair cables.
The differential outputs swing enough to meet RS422/RS485 signal levels at the far end, so the cable side is fine. The scorch mark on a dead board often traces back to a 5V-tolerant part stuffed into a 3.3V socket; this one won't take that hit.
The base product number AM26LV31 covers a family of quad drivers in different packages and temperature grades; the EIDRG4 suffix specifies the 16-SOIC tape-and-reel variant with industrial temperature range.
