GENERAL DESCRIPTION:

The TJA1040 is the interface between the Controller AreaNetwork (CAN) protocol controller and the physical bus.It is primarily intended for high speed applications, up to1 MBaud, in passenger cars. The device providesdifferential transmit capability to the bus and differentialreceive capability to the CAN controller.The TJA1040 is the next step up from the TJA1050 highspeed CAN transceiver. Being pin compatible and offeringthe same excellent EMC performance, the TJA1040 alsofeatures:• An ideal passive behaviour when supply voltage is off• A very low-current standby mode with remote wake-upcapability via the bus.This makes the TJA1040 an excellent choice in nodeswhich can be in power-down or standby mode in partiallypowered networks.

FEATURES:

• Fully compatible with the ISO 11898 standard

• High speed (up to 1 MBaud)

• Very low-current standby mode with remote wake-upcapability via the bus

• Very low ElectroMagnetic Emission (EME)

• Differential receiver with high common-mode range forElectroMagnetic Immunity (EMI)

• Transceiver in unpowered state disengages from thebus (zero load)

• Input levels compatible with 3.3 V and 5 V devices

• Voltage source for stabilizing the recessive bus level ifsplit termination is used (further improvement of EME)

• At least 110 nodes can be connected

• Transmit Data (TXD) dominant time-out function

• Bus pins protected against transients in automotiveenvironments

• Bus pins and pin SPLIT short-circuit proof to battery andground

• Thermally protected.
