The MAX3086ESD+ is a high-performance, half-duplex transceiver from Maxim Integrated, designed to communicate over RS-485 and RS-422 communication networks. It is specifically engineered to withstand the demanding conditions of industrial environments, making it an ideal choice for applications such as factory automation, HVAC systems, and networked industrial devices.

Key Features

• High-Speed Operation: This transceiver is capable of data rates up to 10Mbps, ensuring quick and efficient data communication for time-sensitive applications.
• Extended Temperature Range: With an operating temperature range of -40°C to +85°C, the MAX3086ESD+ is built to reliably perform in extreme environmental conditions.
• Fail-Safe Receiver: The device features a fail-safe receiver that guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled.
• True Fail-Safe Receiver: It increases the receiver's noise margin and failsafe performance by ensuring a logic-high output if the inputs are shorted or open.
• Hot-Swap Capability: The MAX3086ESD+ includes a hot-swap feature that allows for insertion onto a live bus without creating data errors or disruption in communication.
• Integrated Protection: The device offers robust protection against electrostatic discharge (ESD) up to ±15kV (Human Body Model), safeguarding the transceiver against electrical transients.

Applications

• Industrial Control and Automation
• Building Automation
• Networked Security Systems
• Telecommunications

Technical Specifications

The MAX3086ESD+ operates from a single 5V supply and is available in a 14-pin SOIC package. It is designed with a 1/4-unit load receiver input impedance, allowing up to 128 transceivers on the bus. The device also features thermal shutdown and current-limiting circuitry to protect the transceiver from excessive power dissipation.
