illustrate

The LMS202E has two transmitters for RS-232 communication and two receivers. It has a DC-DC converter that allows the device to operate with only a single +5 V power supply. An on-chip DC-DC converter uses four external 0.1μF capacitors to generate dual RS-232 output level compatible internal supplies.

The device complies with EIA/TIA-232E and CCITT V.28 specifications up to 230kbits/sec. The LMS202E is available in 16-pin narrow and wide SOIC packages.

The transmitter outputs and receiver inputs are ± 15kV electrostatic discharge (ESD) protected. The LMS202E survives ± 15kV ESD events when the RS-232 input and output pins are subject to air gap specifications according to the mannequin or IEC 1000-4-2 (EN61000-4-2). It survives ± 8kV discharge when subjected to IEC 1000-4-2 (EN61000-4-2), contact specification. The device is designed for use in harsh environments where ESD is a concern.
