RS-232 Converter

RS-232 is a serial communication protocol used in Computers to send or receive data. RS-232 uses +/- 15V for data communication. Most embedded system need to communicate with Computer using serial port so it should be converted to TTL level voltage. These IC converts RS232 voltage level to and fourth in TTL level. MAX232, HIN232 are 5V logic supported IC and MAX3232 is 3.3V IC
