Data rate is rated at 250 kbps — a moderate speed suited for fieldbus links, Modbus networks, and other low-to-medium throughput applications where signal integrity over longer cable runs matters more than raw throughput. Receiver hysteresis is specified at 25 mV, which helps reject noise on the bus lines in electrically noisy environments without external filtering.
Yes, it is ROHS3 compliant.
Half-duplex — the driver and receiver share the same bus lines, so direction control is handled via the driver enable pin.
