MAX232 IC
MAX232 IC – RS-232 to TTL Voltage Level Converter
The MAX232 IC is a dual driver/receiver IC that converts TTL (Transistor-Transistor Logic) voltage levels to RS-232 standard levels, and vice versa. It is widely used for serial communication between microcontrollers (like Arduino, AVR, PIC, 8051) and RS-232 devices such as PC serial ports, GSM/GPS modules, and other legacy hardware.
 
Key Features:
  • RS-232 to TTL Level Conversion
    Converts between RS-232 voltage levels and 5V TTL logic, making it ideal for microcontroller interfaces.
  • Dual Driver/Receiver Channels
    Supports two transmit and two receive lines, useful for full-duplex communication.
  • Built-in Charge Pump
    Internal voltage doubler and inverter eliminate the need for external dual power supplies.
  • Low Power Consumption
    CMOS design ensures low current draw, suitable for battery-powered devices.
  • Standard DIP-16 Package
    Easy to use on breadboards and perfboards for prototyping.
 
Applications:
  • Microcontroller to PC serial communication
  • Interfacing GSM, GPS, and RFID modules
  • TTL to RS-232 conversion
  • Serial modem communication
  • Embedded system projects with legacy RS-232 ports
  • Data logging and debug interfaces
