Description The LTC®2862/LTC2863/LTC2864/LTC2865 are low power, 20Mbps or 250kbps RS485/RS422 transceivers operating on 3V to 5.
5V supplies that feature ±60V overvoltage fault protection on the data transmission lines during all modes of operation, including power-down.
Low EMI slew rate limited data transmission is available in a logic-selectable 250kbps mode in the LTC2865 and in 250kbps versions of the LTC2862-LTC2864.
Enhanced ESD protection allows these parts to withstand ±15kV HBM on the transceiver interface pins without latchup or damage.
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.
