LTC2863IDD-2#PBF

LTC®2863 is low power RS485/RS422 transceiver 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. 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 failsafe operation improve data communication reliability in electrically noisy environments and in the presence of large ground loop voltages. Suitable applications are supervisory control and data acquisition (SCADA), industrial control and instrumentation networks, automotive and transportation electronics, building automation, security systems and HVAC, medical equipment, lighting and sound system control.

• Guaranteed failsafe receiver operation
• High input impedance supports 256 nodes
• Fully balanced differential receiver thresholds for low duty cycle distortion
• Current limited drivers and thermal shutdown
• Full duplex
• Maximum data rate of 250kbps
• 8-lead (3mm × 3mm) plastic DFN package
• –40°C to 85°C temperature range
• Pin compatible with LT1785 and LT1791
