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.
FEATURES
• ESD Protection for RS-232 I/O Pins
• ±15kV-IEC1000 4-2 (EN61000-4-2) Contact Discharge
• ±8kV-IEC1000 4-2 (EN61000-4-2) Air-Gap Discharge
• ±15kV Human Body Model
• Single +5V Power Supply
• 230 Kbps Data Rate
