Key Features

  • Wide 3 V to 5.5 V supply range enables compatibility with both 3.3 V and 5 V logic systems for versatile RS-232 interfacing
  • Schmitt trigger inputs provide hysteresis for robust noise immunity in electrically noisy industrial and communication environments
  • Dual driver and receiver channels in one package reduce BOM count and board space for multi-channel serial communication designs
  • EIA-232-F / TIA-232-F / V.28 compliance ensures interoperability with standard RS-232 equipment and legacy serial ports

Applications

The MAX3232EIDE4 is widely used in industrial automation, embedded systems, and communication equipment requiring RS-232 serial interfaces operating from 3.3 V or 5 V power supplies. It enables microcontrollers and DSPs to interface with PCs, modems, and legacy serial peripherals via standard DB9/DB25 connectors. Its noise-immune Schmitt trigger inputs also make it suitable for electrically harsh environments such as factory floors and automotive serial communication systems.
