| Circuit Description : |
|
The serial port is an I/O (Input/Output) device. An I/O device is just a way to get data into and out of a computer. There are many types of I/O devices such as serial ports, parallel ports,
Some time we would like to Interfacing between computer and Microcontroller So.we need the serial transmission converted back to RS232 for can be Interface. |

|
|
|
| The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5-V supply. Each receiver converts TIA/EIA-232-F inputs to 5-V TTL/CMOS levels. |
