GENERAL DESCRIPTION

The TJA1040 is the interface between the Controller Area

Network (CAN) protocol controller and the physical bus.

It is primarily intended for high speed applications, up to

1 MBaud, in passenger cars. The device provides

differential transmit capability to the bus and differential

receive capability to the CAN controller.

The TJA1040 is the next step up from the TJA1050 high

speed CAN transceiver. Being pin compatible and offering

the same excellent EMC performance, the TJA1040 also

features:

• An ideal passive behaviour when supply voltage is off

• A very low-current standby mode with remote wake-up

capability via the bus.

This makes the TJA1040 an excellent choice in nodes

which can be in power-down or standby mode in partially

powered networks.
