20Mbpsor250kbpsRS485/RS422transceiversoperating
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 fail-
safe operation improve data communication reliability in
electrically noisy environments and in the presence of
large ground loop voltages.
