### Description

The MAX232E is a dual driver and receiver that includes a capacitive voltage generator to supply RS-232-F compliant voltage levels from a single 5V supply. Each receiver converts RS-232 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/RS-232-F levels.
