ANALOG DEVICES LTC2862AMPS8-2#PBF RS422 / RS485 Transceiver, 250 Kbps, Half Duplex, Idle, Open, Short, 3 to 5.5V Supply, SOIC-8

LTC2862AMPS8-2#PBF is a fault protected 3V to 5.5V RS485/RS422 transceiver with level 4 IEC ESD 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 and noise rejection in the LTC2862A-2. Application includes supervisory control and data acquisition, industrial control and instrumentation networks, automotive and transportation electronics, building automation, security systems and HVAC, medical equipment, lighting and sound system control.
