Description
MAX232 IC is a dual driver/receiver communication IC that converts voltage levels (0 to 5V) of a TTL device to their equivalent RS232 voltage levels (-25 to +25V) and vice versa. This voltage translation is very much required whenever there is a serial communication between TTL devices e.g. microcontroller and RS232 devices e.g. standard PC. The Max 232 IC can be used in computers, modems, printers, fax machines and many more devices.
