5V Dual-Channel RS-232 Transceiver IC with Integrated Charge Pump for Reliable Serial Communication (SOIC-16)

The MAX232DR is a widely used RS-232 transceiver IC designed to provide reliable voltage level conversion between TTL/CMOS logic and RS-232 communication standards. Operating from a single 5V supply, it integrates two drivers and two receivers, making it ideal for full-duplex serial communication in microcontroller-based systems. The internal capacitive charge pump generates the required RS-232 voltage levels, eliminating the need for dual power supplies and simplifying circuit design.

This IC ensures stable communication by converting RS-232 input signals (up to +-30V) into standard logic levels, while its drivers generate compliant output voltages for serial interfaces. With a data rate of up to 120 kbps, the MAX232DR is suitable for a wide range of applications including embedded systems, industrial communication, and legacy serial interfaces. Its robust input thresholds and hysteresis improve noise immunity, ensuring reliable performance in electrically noisy environments.

Key Features

  • Dual Driver and Receiver: Supports full-duplex RS-232 communication
  • Single 5V Supply Operation: No need for dual voltage rails
  • Integrated Charge Pump: Generates RS-232 voltage levels using external capacitors
  • RS-232 Standard Compliance: Meets TIA/EIA-232-F specifications
  • Wide Input Voltage Range: Accepts up to +-30V RS-232 signals
  • TTL/CMOS Compatibility: Seamless interface with microcontrollers
  • Improved Noise Immunity: 1.3V threshold and 0.5V hysteresis (typical)
  • Moderate Data Rate: Supports up to 120 kbps
  • Compact Package: SOIC-16 for easy PCB integration
