The MAX3221CUE is a high-quality integrated circuit from Maxim Integrated, designed to facilitate serial communication in a variety of electronic applications. This particular IC is a single transmitter/single receiver RS-232 and V.28 transceiver which operates from a single 3.0V to 5.5V power supply, making it highly versatile for use in portable and power-sensitive devices.

Key Features

• Low-Voltage Operation: The device operates efficiently across a voltage range from 3.0V to 5.5V, which is ideal for battery-operated and portable applications.
• Low-Power Consumption: It features a low-power shutdown mode that reduces power consumption and extends battery life in portable systems.
• AutoShutdown Plus™ Feature: The MAX3221CUE includes Maxim's unique AutoShutdown Plus feature, which automatically enters a low power shutdown state when the RS-232 cable is disconnected or the connected peripherals are turned off.
• High Data Rate: The device supports data rates up to 250kbps, making it suitable for high-speed serial communication.
• Integrated Charge Pump: The on-chip charge pump circuitry generates the necessary RS-232 voltage levels (+/-10V) from a single low-voltage supply, eliminating the need for multiple power sources.
• ESD Protection: The transceiver includes integrated electrostatic discharge (ESD) protection circuitry, which protects against ESD events exceeding ±15kV using the Human Body Model (HBM).
