Data rate reaches 2.5 Mbps, which is fast enough for most industrial fieldbus and building-automation links running Modbus RTU or similar multi-drop networks. ## Receiver hysteresis and noise margin Built-in 70 mV receiver hysteresis helps reject noise on long cable runs — a practical benefit when the bus stretches across a factory floor or through a noisy electrical cabinet. Full-duplex operation means the device can transmit and receive simultaneously, which is useful for point-to-point links where both directions need to be active at the same time. ROHS3 compliant, which covers the latest EU restriction exemptions and simplifies cross-border shipping.","metaTitle":"MAX490CSA+ RS-485/RS-422 Transceiver, 2.5 Mbps, 8-SOIC","metaDescription":"Analog Devices MAX490CSA+ full-duplex RS-485/RS-422 transceiver, 2.5 Mbps data rate, 8-SOIC package.
