MAX232CSE+

MAX232CSE+ Description

The MAX232CSE+ from Analog Devices Inc./Maxim Integrated is a dual-driver/dual-receiver RS-232 transceiver designed for bidirectional data communication between TTL/CMOS logic levels and RS-232 signals. Housed in a 16-pin SOIC package, this surface-mount IC operates within a 4.5V to 5.5V supply range, making it compatible with standard 5V systems. It supports full-duplex communication at data rates up to 120 kbps, ensuring reliable serial data transmission in industrial, embedded, and consumer applications. With 500 mV receiver hysteresis, it enhances noise immunity, critical for electrically noisy environments.
