Product details

What this RS485 transceiver is and where it fits

The MAX14781EESA+ is a Maxim Integrated half-duplex transceiver supporting both RS422 and RS485 protocols in a single 8-pin SOIC package. It integrates one driver and one receiver.

Temperature grade and deployment environment

Rated for -40°C to 85°C, this part is suited for industrial control panels, outdoor telecom cabinets, and factory-floor I/O blocks that see seasonal temperature swings but not under-hood automotive extremes. The industrial temperature range covers most panel-mounted and DIN-rail applications.

Sourcing and lifecycle

The MAX14781EESA+ carries an Active lifecycle status and is RoHS3 compliant.

Frequently asked questions

Is MAX14781EESA+ full duplex or half duplex?

It is a half-duplex transceiver. The single driver and single receiver share the same bus lines, so the bus must be direction-controlled — typical for RS485 multi-drop networks where only one node talks at a time.

What is the data rate of MAX14781EESA+?

The data rate is 370 kbps. This is a moderate speed suitable for Modbus RTU, BACnet MS/TP, and similar fieldbuses where cable length is more important than raw throughput.
