The MAX232NG4 is a Dual Driver/Receiver includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5V supply. Each receiver converts TIA/EIA-232-F inputs to 5V TTL/CMOS levels. This receiver has a typical threshold of 1.3V, a typical hysteresis of 0.5V and can accept ±30V inputs. Each driver converts TTL/CMOS input levels into TIA/EIA-232-F levels.
