LTC2862AIDD-2#PBF

收发器, RS422, RS485, 20Mbps, 1驱动器, 3 V至5.5 V电源, DFN-8

The from is a ±60V fault protected 3V to 5.5V RS485/RS422 transceiver with Level 4 IEC ESD protection in 8 pin 3mm x 3mm plastic DFN package. The LTC2862A-2 is a Low EMI 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 and EFT protection on the interface pins, increased resistance to electrical overstress, increased receiver noise immunity, additional receiver noise filtering and noise rejection. 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.
