250 kbps data rate — what it means for the bus
At 250 kbps, this part is sized for Profibus DP at the lower baud rates, Modbus RTU, and general-purpose sensor/actuator networks. It will not support 1 Mbps or higher fieldbuses like DeviceNet or CAN at full speed.
Full duplex and 1/1 driver/receiver count
Full-duplex operation means separate transmit and receive pairs, so the bus wiring needs four wires (two twisted pairs) instead of two. The single driver and single receiver limit this part to point-to-point or multi-drop configurations where only one transmitter talks at a time.
Receiver hysteresis — noise margin on long cables
The 70 mV of receiver hysteresis is a deliberate design choice for industrial environments. It prevents the receiver from chattering on a slowly rising differential signal caused by cable capacitance or ground shifts.
Package and footprint
The 10-uMAX/uSOP package (3.00 mm body width, 0.118" pitch) is a common footprint shared with many other single-transceiver parts from Analog Devices.
Lifecycle and compliance
The MAX1481EUB+ is listed as Active and ROHS3 compliant. The ROHS3 compliance covers the full substance restriction set, including all four phthalates.
