Max232 is a converter IC and converts signals from a TIA-232(RS-232) serial port to signals suitable for use in TTL- compatible digital logic circuits typically converts the RX TX CTS RTS signals. This is a dual receiver or dual transmitter. It gives about �7.5V TIA-232 Voltage level output from 5V input by on-chip charge pumps and external capacitors which makes it useful to implement TIA-232 in devices.
The receiver reduces TIA-232 inputs which can be up to �25V to 5V TTL levels. The typical threshold and hysteresis of the receiver is 1.3V and 0.5V respectively.
It is TTL/CMOS to RS232 Converter IC
