The MAX3223EIPWR is a dual-channel RS-232 transceiver IC from Maxim Integrated (now part of Analog Devices), designed to enable reliable serial communication between TTL/CMOS logic and RS-232 standards. It supports bidirectional data conversion for two independent RS-232 channels, facilitating full-duplex operation in industrial and embedded systems. Its compact TSSOP-16 package and robust features make it ideal for space-constrained applications requiring dual RS-232 ports.

Key Features

• Dual-channel RS-232 support: Provides two independent channels for simultaneous full-duplex communication.
• High-speed operation: Supports data rates up to 250 kbps per channel.
• Single-supply operation: Functions with a 3V to 5.5V power supply, simplifying integration.
• Integrated charge pump: Eliminates external capacitors, reducing component count and cost.
• Enhanced ESD protection: Withstands ±15 kV contact discharge for reliability in harsh environments.
• Extended temperature range: Operates from -40°C to +85°C, suitable for industrial use.
• Low-power shutdown mode: Reduces power consumption to <1 µA when inactive.
• Noise immunity and protection: Includes overvoltage and short-circuit protection to safeguard circuits.

Common uses include industrial automation, PLC communication, POS terminals, medical devices, test equipment, networking hardware, and embedded systems requiring dual RS-232 interfaces. Its compact design and dual-channel capability make it ideal for connecting multiple legacy peripherals in rugged or space-limited environments.

The MAX3223EIPWR delivers dual RS-232 channel capability with industrial-grade durability and minimal power consumption. Its integrated charge pump, wide voltage range, and robust protection features make it a cost-effective solution for bridging TTL/CMOS logic to RS-232 in applications demanding reliable, multi-channel serial communication.
