3.3V/5V 4Mbps CAN Transceiver Provides ±60V Fault Protection for
Improved System Reliability
MILPITAS, CA – February 17, 2015 – Linear Technology Corporation introduces the LTC2875,
an exceptionally rugged, high voltage tolerant CAN (controller area network) transceiver to
greatly reduce field failures without the need of costly external protection devices. In practical
CAN systems, installation cross-wiring faults, ground voltage faults or lightning induced surge
voltages can cause overvoltage conditions that exceed absolute maximum ratings of typical
transceivers. The LTC2875 features ±60V overvoltage fault and ±25kV HBM ESD protection on
the data transmission lines, protecting bus pins during operation and shutdown. Whether a circuit
is transmitting, receiving or powered off, the LTC2875 tolerates any voltage within ±60V
without damage, increasing the robustness of typical CAN networks.
CAN bus systems are becoming increasingly popular in industrial controls,
instrumentation networks and automotive electronics. The CAN bus has a well defined protocol
stack, with support for standalone controllers, FPGAs and ASICs, making implementation easier
over alternative interfaces, such as RS485. The LTC2875 provides the flexibility to be powered
from a 3.3V or 5V rail, which is very useful in industrial applications where a 5V rail may not be
present. In addition to the high fault and ESD protection, the device features a low
electromagnetic emission (EME) driver with a transmit data (TXD) dominant timer to prevent
faulty controllers from clamping the bus, as well as a high electromagnetic immunity (EMI)
receiver with an extended ±36V common mode range to enable operation in electrically noisy
environments and in the presence of ground loops. The LTC2875 features a high speed data rate
of 4Mbps with an adjustable slew rate for data rates as low as 1kbps. A shutdown mode brings
all of the LTC2875’s outputs to high impedance and reduces power consumption to 1µA.
The LTC2875 is offered in commercial, industrial, automotive and military (–55°C to
125°C) temperature grades and is available in 3mm x 3mm DFN-8 and SO-8 packages, with
industry-standard pinouts. Pricing starts at $1.72 each in 1,000 piece quantities. Visit
