MAX13087EASA-T RS-485/RS-422 Transceiver from Maxim Integrated

The MAX13087EASA-T is a high-performance, half-duplex transceiver from Maxim Integrated, designed for RS-485 and RS-422 communication protocols. This device is ideal for industrial, network, and telecommunications applications where robust communication is essential. The MAX13087EASA-T offers a slew-rate-limited driver that minimizes electromagnetic interference (EMI) and reduces reflections caused by improperly terminated cables, making it suitable for long-distance communication over twisted-pair cabling.

One of the notable features of the MAX13087EASA-T is its enhanced electrostatic discharge (ESD) protection. It can withstand ESD events up to ±15kV Human Body Model (HBM), ensuring reliability and longevity in harsh environments. This transceiver operates from a single 5V supply, and its operating temperature range of -40°C to +85°C makes it versatile for various industrial temperature applications.

The MAX13087EASA-T supports data rates up to 500kbps and includes a 1/4-unit-load receiver input impedance, allowing up to 128 transceivers on the bus. This feature makes it highly suitable for networked devices in complex systems. Additionally, the device is equipped with a fail-safe feature that guarantees a known state of the receiver output when the inputs are open, shorted, or idle, which enhances fault tolerance.

The transceiver comes in an 8-pin NSOIC package, which is compact and space-efficient for PCB layouts. Its thermal shutdown and short-circuit protection features further contribute to its robust design, safeguarding the device from damage due to excessive temperature and current conditions.

Integrating the MAX13087EASA-T into your design ensures reliable communication with low power consumption and minimal external components, making it a cost-effective solution for a wide range of data transmission applications.
