CAN controller interface
Rev. 06 — 25 August 2011
Product data sheet
1. 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).
