Product details

RS-485/RS-422 transceiver, 2.5 Mbps, 8-SOIC

The MAX490CSA+ is a full-duplex transceiver supporting both RS-422 and RS-485 protocols, with a single driver and single receiver on a 1/1 configuration. 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.
