MAX3227EIDB – TEXAS INSTRUMENTS

The MAX3227EIDB is a low-power, single-channel, RS-485/RS-422 transceiver from Maxim Integrated, packaged in a space-saving 8-pin µMAX® package. It operates from a single 3.0V to 5.5V supply, making it suitable for a wide range of battery-powered applications. The device features ±15kV ESD protection on all pins, crucial for robust industrial environments. Its driver output boasts a high output current of ±300mA, enabling reliable communication over long distances and with multiple receivers. Receiver input hysteresis is typically 200mV, minimizing the risk of false triggering. The MAX3227EIDB incorporates automatic direction control, simplifying circuit design and eliminating the need for external control signals. Common applications include industrial automation, building automation systems, and data acquisition systems requiring robust, long-distance serial communication. Its low power consumption and high ESD protection provide a significant advantage over other transceivers in demanding applications where reliability and longevity are paramount. The device’s compact µMAX package further contributes to its suitability for space-constrained designs.
