MAX1406CWE

MAX1406CWE Description

The MAX1406CWE is a full-duplex RS-232 transceiver from Analog Devices Inc./Maxim Integrated, designed for reliable serial communication in industrial and embedded systems. Housed in a 16-pin SOIC package, this surface-mount IC integrates 3 drivers and 3 receivers, supporting data rates up to 230kbps. Operating within a 4.5V to 5.5V supply range, it is optimized for 5V systems and features 650mV receiver hysteresis for robust noise immunity. With an operating temperature range of 0°C to 70°C, it suits moderate environments. Though marked obsolete, it remains relevant for legacy designs requiring stable RS-232 interfacing.

MAX1406CWE Features

• Full-duplex RS-232 communication with 3 drivers/3 receivers.
• 230kbps data rate for efficient serial data transmission.
• Wide supply voltage (4.5V–5.5V) compatible with standard 5V logic.
• 650mV receiver hysteresis enhances noise rejection in electrically noisy environments.
• Surface-mount 16-SOIC package for compact PCB integration.
• Low moisture sensitivity (MSL 1) ensures reliability during assembly and operation.
• REACH and EAR99 compliant, meeting environmental and export control standards.

MAX1406CWE Applications

• Industrial automation: Reliable RS-232 communication for PLCs, sensors, and control systems.
