I saw this IC **broken link removed** in schematics which i'm reviewing.
I think that it is used to allow communication between RS232 and microcontroller.
However, RS232 requires DC levels of ±12V, and this IC's VCC is ranged from 3V to 5.5V.

I want the PC to interface this IC through a serial port (RS232) cable.
Could you help me figure out how to connect the IC's pins to the RS232 pins?
I read about the RS232's pinout, however I couldnt perform an one-to-one matching.
