Max3232

Max3232
The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal to terminal (serial-port connection terminals, including GND).
What is the voltage level of rs232 serial communication?
Valid RS-232 signals are either in the range of +3 V to +15 V or the range −3 V to −15 V with respect to the common ground (Figure 1-1). To be more specific, the driver output is Logic 0 when the voltage is between +5 V and +15 V and is Logic 1 when the voltage is between -5 V to -15 V.
