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.","metaTitle":"MAX1481EUB+ RS-422/RS-485 Transceiver, Full Duplex, 250 kbps","metaDescription":"MAX1481EUB+ is a full-duplex RS-422/RS-485 transceiver from Analog Devices.
