The TJA1050 is the interface between the Controller Area Network (CAN) protocol
controller and the physical bus. The device provides differential transmit capability to
the bus and differential receive capability to the CAN controller.
The TJA1050 is the third Philips high-speed CAN transceiver after the PCA82C250 and the
PCA82C251. The most important differences are:
- Much lower electromagnetic emission due to optimal matching of the output
signals CANH and CANL
- Improved behaviour in case of an unpowered node
- No standby mode.
This makes the TJA1050 eminently suitable for use in nodes that are in a power-down
situation in partially powered networks.
