The MAX202EESE+T with Maxim Integrated RS-232 Interface IC 15kV ESD-Protected 5V RS232 Transceiver device from Analog Devices is a transceiver IC for low-power, full-duplex asynchronous data transmission over two lines using the RS-232 serial communication protocol. It features a built-in 15 kV ESD protection diode for each board-level I/O, a data rate of up to 230 kbps, a low voltage interface (5V) that works for both power and signal levels, three driver modes (async, half-duplex, sync) for various application flexibility, and a 75-O driver output impedance for enhanced data transmission. It also has a power shutdown mode that automatically saves power when the transceiver is idle. This transceiver is suitable for use in automotive, medical, industrial, and consumer applications that must interface with an RS-232 system.
