The MAX3238CDB is a highly integrated serial communication device from Texas Instruments, designed to facilitate reliable data transmission and reception over UART (Universal Asynchronous Receiver/Transmitter) interfaces. It is a 3-V to 5.5-V multichannel RS-232 line driver/receiver that meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.
Key Features
- Multiple Drivers and Receivers: The MAX3238CDB features five drivers and three receivers, making it highly suitable for serial port applications in desktop, workstation, and server environments where multiple RS-232 connections are required.
- Low Power Consumption: This device operates in a low-power mode, drawing as little as 1μA of supply current when in the shutdown mode, making it ideal for battery-powered and power-sensitive applications.
- Wide Voltage Range: The device supports a wide operating voltage range from 3 V to 5.5 V, providing flexibility for use in various system designs.
- Electrostatic Discharge (ESD) Protection: The MAX3238CDB is equipped with ESD protection up to ±15kV using the IEC 1000-4-2 Air-Gap Discharge method, ±8kV using the IEC 1000-4-2 Contact Discharge method, and ±15kV using the Human Body Model, ensuring robust performance in harsh environments.
- High Data Rate: It supports data rates up to 250 kbps, enabling high-speed data communication for a wide range of applications.
- Automatic Power-Down Feature: The device automatically enters a low-power shutdown state when the RS-232 cable is disconnected or the connected peripherals are powered off, further reducing power consumption.
