Description

General part information

LTC2863 Series

The LTC2862/LTC2863/LTC2864/LTC2865 are low power, 20Mbps or 250kbps RS485/RS422 transceivers operating on 3V to 5.5V supplies that feature ±60V overvoltage fault protection on the data transmission lines during all modes of operation, including power-down. Low EMI slew rate limited data transmission is available in a logic-selectable 250kbps mode in the LTC2865 and in 250kbps versions of the LTC2862-LTC2864. Enhanced ESD protection allows these parts to withstand ±15kV HBM on the transceiver interface pins without latch-up or damage.Extended ±25V input common mode range and full fail-safe operation improve data communication reliability in electrically noisy environments and in the presence of large ground loop voltages.Part NumberDuplexEnablesMax Data RateVLPinLTC2862-1HalfYes20MNoLTC2862-2HalfYes250kNoLTC2863-1FullNo20MNoLTC2863-2FullNo250kNoLTC2864-1FullYes20MNoLTC2864-2FullYes250kNoLTC2865FullYes20M/250kYesApplicationsSupervisory Control and Data Acquisition (SCADA)Industrial Control and Instrumentation NetworksAutomotive and Transportation ElectronicsBuilding Automation, Security Systems and HVACMedical EquipmentLighting and Sound System Control
