LTC2862ACS8-1#PBF

LTC®2862A 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 and an improved failsafe function optimized for high speed in the LTC2862A-1. Low EMI slew rate limited data transmission is available in 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.
