MAX232E Overview
The MAX232E is a dual driver and receiver that includes a capacitive voltage generator to supply RS232-F pliant voltage levels from a single 5-V supply. Each receiver converts RS-232 inputs to 5-V TTL/CMOS levels. This receiver has a typical threshold of 1.3 V, a typical hysteresis of 0.5 V, and can accept ±30-V inputs.
