TJA1050

` Fully compatible with the "ISO 11898" standard
` High speed (up to 1 Mbaud)
` Transmit Data (TXD) dominant time-out function
` Bus lines protected against transients in an automotive environment
` Silent mode in which the transmitter is disabled
` Differential receiver with wide common-mode range for high ElectroMagnetic Immunity (EMI)
` Input levels compatible with 3.3 V devices
` Thermally protected
` Short-circuit proof to battery and ground
` An unpowered node does not disturb the bus lines
` At least 110 nodes can be connected.

The TJA1050 is the interface between the 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 successor to the PCA82C250 high speed CAN transceiver. The most important improvements are: · Much lower ElectroMagnetic Emission (EME) due to optimal matching of the CANH and CANL output signals · Improved behaviour in case of an unpowered node.
