General description

The PCA82C250 is the interface between a CAN protocol controller and the physical bus.

The device provides differential transmit capability to the bus and differential receive

capability to the CAN controller.

2.

Features and benefits

 Fully compatible with the “ISO 11898” standard

 High speed (up to 1 MBd)

 Bus lines protected against transients in an automotive environment

 Slope control to reduce Radio Frequency Interference (RFI)

 Differential receiver with wide common-mode range for high immunity against

ElectroMagnetic Interference (EMI)

 Thermally protected

 Short-circuit proof to battery and ground

 Low-current Standby mode

 An unpowered node does not disturb the bus lines

 At least 110 nodes can be connected

3.

Applications

 High-speed automotive applications (up to 1 MBd).
