• RoHS: Compliant

Product Advantages

The MAX222CWN-T offers a variety of advantages for designers looking for a reliable and efficient communication interface. Its integrated charge pump circuitry eliminates the need for an external ±12V power supply, as it can generate the ±10V needed for RS-232 transmission from a single 5V source. This feature significantly simplifies power supply design and reduces the overall component count, making it an ideal choice for portable applications.

With its low-power shutdown mode, the MAX222CWN-T conserves power when the device is not in use, making it suitable for battery-powered devices such as laptops, PDAs, and other mobile communication equipment. Additionally, the device is capable of handling data rates up to 120kbps, allowing for efficient data transfer without compromising signal integrity.

Applications

The versatile nature of the MAX222CWN-T makes it suitable for a broad range of applications. It is commonly used in:

• Portable Computing Devices
• Battery-Powered Equipment
• Handheld Communications Devices
• Peripheral Interfaces
• Data Acquisition Systems

In summary, the Maxim Integrated MAX222CWN-T is a robust RS-232 interface solution that offers high data rate capability, low-power operation, and a compact surface mount package, making it an excellent choice for designers who require a reliable and space-efficient communication interface.
