Maxim Integrated's MAX232AEPE Interface IC

The MAX232AEPE from Maxim Integrated is a highly reliable dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. This integrated circuit (IC) is designed to interface with RS-232 communication ports, providing the necessary voltage conversion for data signal levels.

The MAX232AEPE is equipped with two drivers and two receivers, making it an ideal choice for serial communications in a variety of applications, including but not limited to modems, computers, and peripherals. Its design ensures that it can operate with a wide range of external capacitors, with the recommended value being 1.0μF for the version covered by this product, although values up to 10μF can be used for improved performance in noisy environments.

Key Features:

• Voltage Range: Operates from a single 5V power supply, with a typical 5V operating voltage.
• Driver/Receiver Channels: Contains two drivers and two receivers, supporting full-duplex communication.
• Electrostatic Discharge (ESD) Protection: Provides ESD protection exceeding ±15kV using the Human Body Model (HBM), ensuring robust performance in harsh environments.
• Data Rate: Capable of up to 120kbps data rate, suitable for many serial communication applications.
• Low Power Shutdown: Features a low power shutdown mode which reduces power consumption when not in active use.
• Capacitor Voltage Generation: Integrated charge pump circuitry eliminates the need for multiple power supplies, using external capacitors to generate the necessary RS-232 voltage levels.

Applications:

• Battery-Powered Systems
• Terminals
• Modems
• Computers and Peripherals

The MAX232AEPE comes in a 16-pin plastic DIP (PDIP) package, offering a robust solution for through-hole mounting on printed circuit boards. Its operating temperature range is from 0°C to 70°C, making it suitable for commercial-grade applications. With its proven reliability and Maxim Integrated's commitment to quality, this IC is a go-to choice for designers seeking to implement RS-232 interfaces with minimal external components and straightforward design-in processes.
