PCA82C250
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).
