Maxim Integrated MAX13087EESA+ RS-485/RS-422 Transceiver
The Maxim Integrated MAX13087EESA+ is a high-performance, half-duplex transceiver designed for RS-485 and RS-422 communication protocols. This device is engineered to provide reliable data transmission over long distances and in electrically noisy environments, making it an ideal choice for industrial, network, and automation applications.
The MAX13087EESA+ operates from a single 5V supply and features a proprietary low-dropout transmitter output stage, delivering a full driver output swing for data rates up to 500kbps. This ensures robust communication in differential signaling applications, even with the presence of heavy loading and long cable runs.
One of the key features of this transceiver is its enhanced Electrostatic Discharge (ESD) protection. The device is protected up to ±15kV for both Human Body Model (HBM) and IEC 1000-4-2 Air-Gap Discharge, ensuring high reliability and resilience in harsh environments. Additionally, it includes fail-safe circuitry, which 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 transmitters disabled.
The MAX13087EESA+ also incorporates a thermal shutdown feature to protect the device from excessive power dissipation that could lead to high temperatures damaging the transceiver. This thermal protection is especially critical in situations where fault conditions occur on the data lines.
For design flexibility, the transceiver includes a low-power shutdown mode that reduces the supply current to less than 1µA, extending the life of battery-powered systems. Its small 8-pin NSOIC package makes it suitable for space-constrained applications.
Additional features of the MAX13087EESA+ include a 1/4-unit-load receiver input impedance, which allows up to 128 transceivers on the bus, and a wide common-mode voltage range, making the device tolerant to ground potential shifts. With its robust design and advanced features, the Maxim Integrated MAX13087EESA+ transceiver is a reliable solution for any application requiring high-speed, bidirectional data communication.
