It is not 5V-tolerant on the supply or I/O, so a mixed 5V/3.3V backplane needs level translation on the driver inputs. The narrow window also means a 3.0V LDO output at the low end still holds the driver within spec, but a 2.8V rail would not — check your regulator tolerance against the 3V minimum.
ROHS3 compliance is confirmed, covering EU and most global regulatory requirements.
Yes, the AM26LV31ID is specified for both RS422 and RS485 protocols. It is a quad driver (4 drivers, 0 receivers), so it handles the transmit side of an RS485 bus. For a full RS485 transceiver you would pair it with a separate receiver, but the driver itself is protocol-compliant.
