High speed CAN transceiver
TJA1040
FEATURES
GENERAL DESCRIPTION
• Fully compatible with the ISO 11898 standard
• High speed (up to 1 MBaud)
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.
• Very low-current standby mode with remote wake-up
capability via the bus
• Very low ElectroMagnetic Emission (EME)
• Differential receiver with high common-mode range for
ElectroMagnetic Immunity (EMI)
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:
• Transceiver in unpowered state disengages from the
bus (zero load)
• Input levels compatible with 3.3 V and 5 V devices
• An ideal passive behaviour when supply voltage is off
• Voltage source for stabilizing the recessive bus level if
• A very low-current standby mode with remote wake-up
split termination is used (further improvement of EME)
capability via the bus.
• At least 110 nodes can be connected
This makes the TJA1040 an excellent choice in nodes
which can be in power-down or standby mode in partially
powered networks.
• Transmit Data (TXD) dominant time-out function
• Bus pins protected against transients in automotive
environments
• Bus pins and pin SPLIT short-circuit proof to battery and
ground
• Thermally protected.
