MAX3221CPWE4 – TEXAS INSTRUMENTS

The MAX3221CPWE4 is a low-power, single-channel RS-485/RS-422 transceiver from Maxim Integrated, packaged in a space-saving 8-pin TSSOP. Operating from a 2.7V to 5.5V supply voltage, it features ±15kV ESD protection on all pins, crucial for robust industrial applications. Its driver boasts a high output current of ±30mA, ensuring reliable signal transmission over long distances. The receiver features a low input bias current (<1µA) minimizing power consumption and maximizing signal integrity. Unlike some competitors, the MAX3221CPWE4 incorporates internal bias resistors, simplifying design and reducing external component count._x000D_ _x000D_ This transceiver excels in applications requiring reliable, long-distance serial communication in noisy environments. Common use cases include industrial automation, process control systems, and building automation where robust data transmission is paramount. Its low power consumption is particularly advantageous in battery-powered or energy-constrained systems. The device's fail-safe mechanism, automatically disabling the driver when the receiver detects a fault, enhances system reliability. The 8-pin TSSOP package contributes to smaller PCB footprints, making it ideal for space-constrained designs. Its wide operating voltage range ensures compatibility across diverse power supply architectures.
