Product details

RS-485 bus transceiver for 5 V industrial links

The MAX489EESD+T is a full-duplex RS-485/RS-422 transceiver from Analog Devices, packing one driver and one receiver into a 14-SOIC package.

250 kbps data rate and 70 mV hysteresis — what they mean on the bus

Rated for 250 kbps, this transceiver handles the common baud rates for Modbus RTU, Profibus DP at lower speeds, and many proprietary RS-485 sensor networks. Full-duplex operation means the driver and receiver are active simultaneously, so the part can transmit and receive on separate twisted pairs without direction switching. This simplifies the firmware compared to half-duplex parts that need a transmit-enable toggle on every packet.

Frequently asked questions

What protocols does MAX489EESD+T support?

It supports both RS-422 and RS-485 protocols in full-duplex mode. The single driver and single receiver pair handles point-to-point or multi-drop RS-485 networks with proper termination.

What is the data rate of MAX489EESD+T?

The data rate is 250 kbps, suitable for Modbus RTU at common baud rates and many industrial sensor buses that do not require higher speed.

What compliance documentation does Analog Devices provide for MAX489EESD+T?

Analog Devices provides RoHS3 compliance documentation for the MAX489EESD+T. The part is fully RoHS compliant and free from restricted substances per EU Directive 2011/65/EU.
