Key Features

  • Operates from 3V to 5.5V supply voltage, compatible with both 3.3V and 5V logic systems
  • Dual RS-232 drivers and receivers (2Tx/2Rx) in a compact 16-pin SOIC package
  • Schmitt trigger inputs for enhanced noise immunity on receive lines
  • Meets EIA-232-F / TIA-232-F / V.28 interface standards
  • Low standby current for power-sensitive embedded applications

Applications

The MAX3232IPW is widely used in industrial and embedded systems for UART-to-RS-232 level conversion, connecting microcontrollers and FPGAs to serial ports on PCs and legacy equipment. It is also common in point-of-sale terminals, GPS modules, and barcode scanners that require reliable RS-232 communication. Its wide supply range makes it ideal for battery-powered and mixed-voltage designs.
