Key Features
- 15 kV ESD protection on bus pins safeguards RS-485/RS-422 lines in industrial environments with high electrostatic discharge risk
- 10 Mbps maximum data rate with slew-rate limiting reduces EMI emissions on long cable runs in noise-sensitive RS-485 networks
- Fail-safe differential Schmitt trigger inputs guarantee defined logic output when bus lines are open, shorted, or idle with no active driver
Applications
The MAX3087EEPA+ is used in industrial RS-485 networks, building automation systems (BACnet, Modbus), and factory floor data acquisition wiring where long cable runs of up to 1200 meters require robust differential signaling. Its 15 kV ESD protection and fail-safe inputs make it well suited for outdoor instrumentation, process control PLCs, and energy metering equipment exposed to electrostatic discharge and cable faults.

Frequently Asked Questions
What is the maximum data rate supported by the MAX3087EEPA+ on an RS-485 bus?
The MAX3087EEPA+ supports data rates up to 10 Mbps on RS-485 and RS-422 differential buses, while its built-in slew-rate limiting reduces high-frequency EMI emissions on cable runs. For longer cable distances exceeding 100 meters, lower baud rates are recommended to maintain signal integrity, but the device handles up to 256 nodes on a single RS-485 bus segment.
How does the 15 kV ESD protection on the MAX3087EEPA+ benefit industrial RS-485 installations?
Industrial RS-485 cable runs regularly accumulate electrostatic charge from nearby machinery, long cable routing, and outdoor installations, exposing bus transceivers to surge events exceeding 8 kV. The MAX3087EEPA+ withstands 15 kV human-body model ESD on its A and B bus pins, preventing latch-up and device damage in PLC panels, motor drives, and process control networks operating in environments with high electrical noise and infrequent but damaging ESD events.
Under what bus fault conditions does the fail-safe feature of the MAX3087EEPA+ protect system communication?
The fail-safe differential Schmitt trigger receiver in the MAX3087EEPA+ guarantees a logic HIGH output when the RS-485 bus is in an open-circuit, short-circuit, or fully idle (no active driver) state. This prevents the receiver output from floating or toggling unpredictably when all 256 bus nodes are in tristate, which would corrupt UART data framing in Modbus RTU or BACnet MSTP protocols at baud rates from 9600 bps up to 10 Mbps.
