Maxim Integrated MAX487ESA+T RS-485/RS-422 Transceiver

The MAX487ESA+T from Maxim Integrated is a low-power transceiver for RS-485 and RS-422 communication. It features a half-duplex communication capability that enables data transmission and reception on a single pair of wires, making it ideal for cost-sensitive and space-constrained applications.

This transceiver is designed to operate with a single 5V power supply, and it draws a very low supply current when in idle mode, which is typically 300µA, making it suitable for energy-efficient systems. Additionally, the MAX487ESA+T includes a shutdown feature that reduces the supply current to 0.1µA, further conserving power when the device is not in active use.

With its extended ESD protection, the MAX487ESA+T is capable of withstanding ±15kV electrostatic discharge (ESD) strikes without sustaining any damage, thereby offering robust performance in harsh industrial environments. The device is also fully compliant with the TIA/EIA-485-A standard, ensuring compatibility with a wide range of industry-standard communication protocols.

The MAX487ESA+T operates over a wide temperature range of -40°C to +85°C, making it a reliable choice for various applications, including industrial control systems, HVAC controls, data acquisition systems, and networked devices in building automation.

Featuring a driver differential output and receiver input sensitivity of ±200mV, the transceiver ensures reliable data transmission even over long cable runs or in electrically noisy environments. The device can also be connected to up to 128 transceivers on the same bus, allowing for extensive networking possibilities.

Available in an 8-pin SOIC package, the MAX487ESA+T is designed for ease of implementation into existing designs. Its small footprint and industry-standard pinout make it a convenient drop-in solution for many communication systems requiring robust and efficient data transmission capabilities.

Overall, the Maxim Integrated MAX487ESA+T transceiver is an excellent choice for designers looking for a reliable, low-power solution for RS-485 or RS-422 communication in a variety of applications.
