MAX3223ECDB Description

The MAX3223ECDB from Texas Instruments is a 3V to 5.5V-powered, full-duplex RS-232 transceiver designed for robust serial communication in industrial and embedded systems. Housed in a compact 20-pin SSOP package, this 2-driver/2-receiver IC supports data rates up to 500kbps, making it suitable for moderate-speed data transmission. It operates within a 0°C to 70°C temperature range and features 500mV receiver hysteresis for enhanced noise immunity. The device is RoHS3 compliant and REACH unaffected, aligning with environmental regulations.

MAX3223ECDB Features

• Wide Voltage Range (3V–5.5V): Enables compatibility with both 3.3V and 5V systems.
• Low Power Consumption: Optimized for battery-powered or energy-efficient applications.
• Enhanced Noise Immunity: 500mV receiver hysteresis minimizes errors in noisy environments.
• Full-Duplex Communication: Simultaneous bidirectional data transfer for efficient system design.
• Compact SSOP Package: Saves board space in space-constrained designs.
• Compliance: RoHS3 and REACH compliant, ensuring adherence to global environmental standards.

MAX3223ECDB Applications
