CAN transceiver for 24 V systems

PCA82C251 is a CAN transceiver that is primarily used for applications up to 1 MBd in trucks and buses. Fully compatible with the “ISO 11898-24 V” standard, this transceiver provides differential transmit capability to the bus and differential receive capability to the CAN controller.

It has a feature that prevents destruction of the transmitter output stage. This feature is a current-limiting circuit that protects the transmitter output stage against short-circuits to positive and negative battery voltage.
