FeaTures DescripTion
±60V Fault Protected
3.3V or 5V 25kV ESD
High Speed CAN Transceiver
The LT C
®
2875 is a robust high speed, low power CAN
transceiver operating on 3.3V or 5V supplies that features
±60V overvoltage fault protection on the data transmission
lines during all modes of operation, including power-down.
The maximum data rate has been extended to 4Mbps to
support high speed protocols based on the CAN physi
-
cal layer. Enhanced ESD protection allows these parts to
withstand ±25kV HBM on the transceiver interface pins
without latchup or damage.
Extended ±36V input common mode range and high com
-
mon mode rejection
on the CAN receiver provides tolerance
of large ground loop voltages. A sophisticated CAN driver
with active symmetry control maintains tight control of
the common mode voltage for excellent electromagnetic
emission, while the variable slew rate and split termination
support allow additional EME reduction.
