At 500 kbps, this transceiver handles most PROFIBUS-DP, Modbus RTU, and BACnet MS/TP links. The 100 mV receiver hysteresis provides a clean logic transition on long runs.
The 8-SOIC footprint is industry-standard.

The MAX3084ESA+ is rated for a data rate of 500 kbps, suitable for industrial RS-485 networks like Modbus RTU and PROFIBUS-DP at standard baud rates.
No, the MAX3084ESA+ requires a 5V supply (4.75V to 5.25V) and its logic inputs and outputs are referenced to that rail. It is not directly compatible with 3.3V logic levels without external level translation.
Both are pin-compatible full-duplex RS-485 transceivers in 8-SOIC. The MAX3084ESA+ is rated for 500 kbps, while the MAX3085ESA+ supports up to 10 Mbps. If your application requires higher throughput, the MAX3085ESA+ is a drop-in replacement.
Yes, the MAX3084ESA+ is ROHS3 compliant.
