MAX232 IC is widely used for serial
communication among Microcontrollers & PC. The main function of this
integrated circuit is to change the logic levels of TTL/CMOS
to RS232 throughout the serial communication process.
Generally, a microcontroller works at
TTL of about 0 to 5V while a computer operates on the standards of RS232 like
-25 to +25V. So interfacing a computer with a microcontroller is not possible
without a MAX232 IC. For example; if you want to connect
a microcontroller to the serial pin of a laptop, then you must place
MAX232IC among them.
