XR19L220 1-Channel Integrated UART And RS-232 Transceiver
The XR19L220 (L220) is a highly integrated device that combines a full-featured single channel Universal Asynchronous Receiver and Transmitter (UART) and an RS-232 transceiver. The L220 is designed to operate with a single 3.3V or 5V power supply. The L220 is fully compliant with EIA/TIA-232-F Standards from a +3.0V to +5.5V power supply. 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
