The MAX232 is an integrated circuit that converts the signals from a RS-232 protocol serial port to signals compatible with TTL or Cmos levels and vice versa, this for use in logic control circuits, which has a very special utility since it In control electronics, it is often necessary to exchange data between logic systems and power control systems, which are often far apart, so that communication is severely affected the more extensive the communication. distance between the control system and the power system and due to factors such as signal loss in the communication cables, inductance, interference etc, so to avoid all this it is necessary to convert the low voltage ttl or CMOS logic signals to standard rs232, and which work with voltage parameters of +/- 25v, thus reducing the signal/noise ratio, for this reason the max232 is useful as an interface for To transfer all the information between the two systems, but it is also useful to extract the data from the system LOG on television boards of certain generations that work with the rs232 protocol or even to program microcontrollers without the use of programming stations. So the MAX232 serves as a very convenient data transmit and receive interface for RX (receive data), TX (transmit data), and even CTS (clear to send) and RTS (request to send) signals. Therefore, the chip has two sets of independent data transmission and reception drivers.
