Exar Corporation XR19L200
The XR19L200 (L200) is a highly integrated device that combines a single channel Universal Asynchronous Receiver and Transmitter (UART) and an RS-232 transceiver. The L200 is designed to operate with a single 3.3V or 5V power supply. The L200 is fully compliant with EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply.| Part No. | XR19L200 |

GENERAL DESCRIPTION
The device operates at 250 Kbps data rate with worst case 3K ohms load. Both RS-232 driver outputs and receiver inputs can operate in harsh electrical environments of +/-15V without damage and can survive multiple +/-15kV ESD on the RS-232 lines, while maintaining RS-232 output levels. The L200 operates in three different modes: Awake, Partial Sleep, and Full Sleep. Each mode can be invoked via hardware or software. In the Awake mode, all functions are active. In the Partial Sleep mode, the internal crystal oscillator or charge pump is turned off. In Full Sleep mode, the internal crystal oscillator and the charge pump is shut down. All the RS-232 receivers remain active in any of these four modes.APPLICATIONS
