Product details

RS-485/422 full-duplex transceiver, 25 Mbps

The MAX14789EGSA+: It supports data rates up to 25 Mbps, making it suitable for high-speed industrial communication links such as fieldbus backplanes, motor drive interfaces, and PLC I/O networks. The wide supply range simplifies BOM consolidation when mixing supply voltages on the same bus.

Industrial temperature range and receiver noise margin

The full-duplex topology means the driver and receiver operate simultaneously over two twisted pairs, doubling throughput compared to half-duplex implementations that require direction toggling. This is a direct fit for point-to-point or multi-drop RS-422 links and for RS-485 networks where the master and slave each have dedicated transmit and receive paths.

Package, footprint, and compliance

Supplied in tube format, it is suited for prototype builds and low-to-medium volume production without reel fees. Analog Devices lists the MAX14789EGSA+ as ROHS3 compliant, meeting the latest EU restriction exemption levels.

Frequently asked questions

What is the data rate of this RS-485/RS-422 transceiver?

The MAX14789EGSA+ supports data rates up to 25 Mbps. At this speed, the rise time is fast enough for high-frequency signaling but requires proper termination and stub-length control on the PCB to maintain signal integrity.

What compliance documentation does Analog Devices provide for the MAX14789EGSA+?

Analog Devices certifies the MAX14789EGSA+ as ROHS3 compliant. Standard documentation includes the datasheet with electrical characteristics, package outline drawing, and the ROHS declaration of compliance.
