MAX202IDWR Description

The MAX202IDWR from Texas Instruments is a high-performance RS-232 transceiver designed for robust serial communication in industrial and embedded systems. Housed in a 16-pin SOIC package, this surface-mount (SMD) IC operates within a 4.5V to 5.5V supply range, making it compatible with standard 5V logic systems. It supports full-duplex communication at data rates up to 120 kbps, ensuring reliable data transmission in noisy environments. The device integrates two drivers and two receivers, providing bidirectional communication capability while adhering to RS-232 voltage levels (±5V to ±15V). With 500 mV receiver hysteresis, it offers enhanced noise immunity, critical for industrial automation and telecom applications.
