The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply -232-F voltage levels
Each receiver converts 232-F inputs to 5-V TTL/CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs. Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels.Used for Voltage level conversion between RS232 and TTL compatible devices. Can also be used for Negative voltage reference generation.The MAX232 device is a dual driver/receiver thatincludes a capacitive voltage generator to supplyTIA/EIA-232-F voltage levels from a single 5-Vsupply.
