IC MAX232 is used for TTL/CMOS to RS232 conversion. Meaning most of our Microcontrollers (PIC/ARM/Atmel) operates on TTL/CMOS logic that is it communicates through either 0V or +5V, but our computers work with the help of RS232 which operates at logic level -24V or +24V. So, if we have to interface these microcontrollers with Computer we need to convert the TTL/CMOS logic to RS232 logic. Hence if you are looking for an IC to perform this conversion and interface a Microcontroller with your computer then MAX232 IC is the right one for you.

Pin Configuration

  1. C1 +: Connects to the positive end of First capacitor
  2. V+: Connects to one end of the capacitor & other end is grounded
  3. C1 -: Connects to the negative end of First Capacitor
  4. C2+: Connects to positive end of second capacitor
  5. C2-: Connects to negative end of second capacitor
  6. V-: Connects to one end of the capacitor & other end is grounded
  7. T2 OUT: Transmission pin of second converter module for RS232 cable
  8. R2 IN: Reception pin of second converter module for RS232 cable
  9. R2 OUT: Reception pin of second converter module for Microcontroller(Rx
  10. T2 IN: Transmission pin of second converter module for Microcontroller(Tx)
  11. T1 IN: Transmission pin of first converter module for Microcontroller(Tx)
  12. R1 OUT: Reception pin of first converter module for Microcontroller(Rx)
  13. R1 IN: Reception pin of first converter module for RS232 cable
  14. T1 OUT: Transmission pin of first converter module for RS232 cable
  15. Ground: Connects to the ground of the circuit
  16. Vcc: Connects to the supply voltage typically +5V
