It integrates one driver and one receiver in an 8-pin SOIC package, with a data rate of 115 kbps—sufficient for most Modbus RTU, BACnet MS/TP, and similar fieldbus links.
Receiver hysteresis of 50 mV provides noise immunity on long cable runs, reducing the likelihood of bit errors from ground shifts or coupled interference.
