The MAX487MJA from Maxim Integrated is a premier solution designed for RS-485 and RS-422 communication protocols. This integrated circuit is specifically engineered to provide reliable data transmission in multi-point networks while maintaining low power consumption and enhanced electrostatic discharge (ESD) protection.

Key Features

• Low Quiescent Current: The device operates with a very low supply current, typically 120µA, making it suitable for power-sensitive applications.
• Slew-Rate Limiting: This feature reduces radiated emission levels and prevents data corruption caused by reflections, ensuring error-free communication over long cable runs.
• Extended ESD Protection: The MAX487MJA is equipped with an ESD protection circuit that can withstand up to ±15kV, safeguarding the transceiver against static electricity and other transient voltage spikes.
• Half-Duplex Communication: The transceiver supports bidirectional communication on a single twisted-pair, which simplifies network architecture and reduces cabling costs.
• Wide Common-Mode Range: The device can handle common-mode voltages from -7V to +12V, providing robust performance in electrically noisy environments or in the presence of ground potential differences.

Applications

The MAX487MJA is ideal for a variety of applications where low-power operation and reliable data transmission are essential. These applications include, but are not limited to, industrial control systems, building automation, networked security systems, and data acquisition systems. Its small footprint and robust feature set also make it a perfect choice for portable and compact designs.

Package and Temperature Range

Maxim Integrated offers this transceiver in a CERDIP-8 package, ensuring reliable operation in a wide temperature range of -55°C to +125°C. This makes the MAX487MJA an excellent choice for harsh industrial environments where temperature extremes are common.
