XR19L220 - SINGLE CHANNEL INTEGRATED UART AND RS-232 TRANSCEIVER

Description

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.

Features

  • Meets true EIA/TIA-232-F Standards from +3.0V to +5.5V operation.
  • Up to 250 Kbps data transmission rate.
  • 45us sleep mode exit (charge pump to full power).
  • ESD protection for RS-232 I/O pins at.
  • +/-15kV - Human Body Model +/-15kV - IEC 1000-4-2, Air-Gap Discharge +/- 8kV - IEC 1000-4-2, Contact Discharge.
  • Software compatible with industry standard 16550 UART.
  • Intel/Motorola bus select.
  • Complete modem interface.

www.DataSheet4U.com OCTOBER 2006 XR19L220 SINGLE CHANNEL INTEGRATED UART AND RS-232 TRANSCEIVER REV. 1.0.0 GENERAL DESCRIPTION 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.
