LTC2862ACDD-1#PBF

LTC2862ACDD-1#PBF is a half duplex, low-power 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 and an improved failsafe function optimized for high speed in the LTC2862A-1. 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. It is used in applications such as 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.
