Maxim Integrated's MAX3221CUE-T: RS-232 Transceiver with AutoShutdown

The MAX3221CUE-T is a high-performance, low-power RS-232 transceiver from Maxim Integrated, designed to facilitate serial communication in a variety of digital devices. This integrated circuit is an ideal solution for applications that require a single driver/receiver and operate within the 3V to 5.5V range. It is particularly well-suited for battery-powered devices due to its low-power consumption and AutoShutdown™ feature.

Key Features:

• Single RS-232 Transceiver: The MAX3221CUE-T contains one driver and one receiver, making it perfect for simple point-to-point communication.
• Low Power Consumption: It operates with a low supply current, typically 300µA, which is ideal for extending battery life in portable devices.
• AutoShutdown Plus™: This feature automatically enters a low-power shutdown mode when the RS-232 cable is disconnected or the connected peripherals are turned off, reducing the supply current to just 1µA.
• Wide Voltage Range: The device is designed to work with a supply voltage range of 3V to 5.5V, providing flexibility for various system designs.
• Electrostatic Discharge (ESD) Protection: The MAX3221CUE-T offers a high level of ESD protection, up to ±15kV using the Human Body Model, ensuring robustness and reliability in harsh environments.
• Flow-Through Pinout: The transceiver's flow-through pinout simplifies PCB layout and reduces cross-talk by separating the TIN, TOUT, RIN, and ROUT pins.

Applications:

The MAX3221CUE-T RS-232 transceiver is versatile and can be used in a wide array of applications, including but not limited to:

• Portable or Compact Devices
• Battery-Powered Equipment
• Notebooks, Laptops, and PDAs
• Peripherals
• Point-of-Sale Systems

With its small 16-pin TSSOP package, the MAX3221CUE-T is also space-efficient, making it an excellent choice for designs where board space is at a premium. Its combination of power efficiency, ESD protection, and AutoShutdown Plus™ technology makes it a reliable and energy-conscious choice for modern electronic communication interfaces.
