MAX3232IDE4 Texas Instruments Integrated Circuit (Small Outline Packages) In Stock

What are the key features of MAX3232IDE4?

• Dual RS-232 driver and receiver channels operating from 3 V to 5.5 V supply, enabling direct interfacing between 3.3 V logic MCUs and legacy RS-232 serial equipment
• Schmitt trigger inputs with hysteresis providing clean digital output from slow-edged or noisy RS-232 line signals at data rates up to 250 kbit/s
• EIA-232-F / TIA-232-F / V.28 compliant output levels ensuring compatibility with all standard RS-232 DCE and DTE equipment
• Internal charge pump requiring only four small external capacitors (typically 100 nF) to generate ±5.5 V RS-232 drive levels from a single 3.3 V or 5 V supply

What is MAX3232IDE4 used for?

The MAX3232IDE4 is used to bridge 3.3 V or 5 V UART ports on microcontrollers to legacy RS-232 serial ports on industrial PLCs, test equipment, barcode scanners, and PC serial interfaces. Its 3 V supply compatibility makes it ideal for low-power embedded systems where a 5 V rail is unavailable, such as battery-operated data loggers communicating with RS-232 GPS modules or Modbus RTU instruments. The device is also common in IoT gateways, panel PCs, and industrial single-board computers that must maintain backward compatibility with RS-232 sensors and actuators.
