Linear Technology Corporationintroduces 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.
