General Description

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

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

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