The LTC2862A is a low power, 20Mbps or 250kbps RS485/RS422 transceiver operating on 3V to 5.5V supplies with ±60V overvoltage fault protection on the interface pins during all modes of operation, including power-down. Improvements were made to the LTC2862 for greater robustness and signal integrity: ±40kV HBM and Level 4 IEC ESD protection on the interface pins; increased resistance to electrical overstress; increased receiver noise immunity; additional receiver noise filtering on the LTC2862A-2; and an improved failsafe function optimized for high speed in the LTC2862A-1 and noise rejection in the LTC2862A-2. Low EMI slew rate limited data transmission is available in the 250kbps LTC2862A-2 option, while the LTC2862A-1 operates to 20Mbps.Extended ±25V input common mode range and full failsafe operation improve data communication reliability in electrically noisy environments and in the presence of large ground loop voltages.APPLICATIONSSupervisory Control and Data Acquisition (SCADA)Industrial Control and Instrumentation NetworksAutomotive and Transportation ElectronicsBuilding Automation, Security Systems and HVACMedical EquipmentLighting and Sound System Control
