The MAX221ECAE is a high-performance RS-232 transceiver from Maxim Integrated, designed to meet the demands of modern serial communication applications. This robust transceiver integrates features that make it ideal for portable devices, including low-power consumption and a compact package.

Key Features

• Integrated Charge Pump Circuitry: This feature allows the MAX221ECAE to operate from a single 5V supply while generating RS-232 compliant ±10V output levels, eliminating the need for additional power supplies.
• Low Power Shutdown Mode: To conserve power, the device can enter a shutdown mode that reduces the supply current to 1µA, making it suitable for battery-operated applications.
• High Data Rate: The device supports data rates up to 120kbps, ensuring compatibility with high-speed communication requirements.
• Electrostatic Discharge (ESD) Protection: The MAX221ECAE offers built-in ESD protection up to ±15kV, providing robustness against static electricity and enhancing system reliability.
• Dual Charge Pump: The dual charge pump design requires only four small 0.1µF external capacitors, which reduces the overall footprint and component count on the PCB.

Applications

The MAX221ECAE is versatile and can be used in a variety of applications, including:

• Notebook, Subnotebook, and Palmtop Computers
• Battery-Powered Equipment
