Микросхемы и комплектующие LTC2862AMPS8-2#PBF

Приемопередатчик , RS422, RS485, 20Мб/с, 1 драйвер, 3В до 5.5В питание, NSOIC-8

The LTC2862AMPS8-2#PBF from Linear Technology is a ±60V fault protected 3V to 5.5V RS485/RS422 transceiver with Level 4 IEC ESD protection in 8 pin plastic SOIC 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.
