The MAX231CWE is a high-performance, dual driver/receiver that integrates a charge pump to generate RS-232 voltage levels from a single 5V supply. Manufactured by Maxim Integrated, this integrated circuit is designed to meet the stringent specifications of EIA/TIA-232 and V.28/V.24 communications interfaces while being used in applications with limited space that require reliable data transmission.

Key Features

• Single +5V Power Supply: The device operates on a single 5V power source, which simplifies power supply design and minimizes the need for multiple voltage rails.
• Integrated Charge Pump: The on-chip charge pump circuitry generates the necessary RS-232 voltage levels (+/-10V) from the 5V input, eliminating the need for external capacitors.
• Dual Driver/Receiver Configuration: The MAX231CWE contains two drivers and two receivers, providing the capability to interface with two RS-232 communication lines simultaneously.
• Low Power Shutdown: It features a low-power shutdown mode that reduces power consumption and extends battery life in portable applications.
• Electrostatic Discharge (ESD) Protection: The device includes built-in ESD protection circuitry, safeguarding it against electrostatic discharges.
• High Data Rate: Supports data rates up to 120kbps, making it suitable for high-speed serial communication.

Applications

The MAX231CWE is ideal for use in a variety of applications that require RS-232 communications, such as:

• Portable Computing Devices
• Low-Power Modems
• Battery-Powered Equipment
• Point-of-Sale (POS) Systems
• Peripheral Device Interfaces
