TTL/CMOS, RS232 LOGIC CONVERTER

This s a simple TTL/CMOS . RS232 logic converter. That is it convert TTL/CMOS to RS232 as RS232 to TTL/CMOS logic. It is used t synchronous PIC microcontroller with USART. TTL is -5 t +5V and RS232 is -30 t +30. MAX232 is a dual/receiver. It include capacitive voltage generator to make RS232 logic level from a 5V supply.Each receiver in the MAX232 convert RS232 input into TTL/CMOS(5V). As each driver in the MAX232 convert TTL/CMS input into RS232 logic level. The four capacitors used for this conversion.
