Rev. 04 — 25 August 2011
Product data sheet
1. General description
The PCA82C251 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 11898-24 V” standard
Slope control to reduce Radio Frequency Interference (RFI)
Thermally protected
Short-circuit proof to battery and ground in 24 V powered systems
Low-current Standby mode
An unpowered node does not disturb the bus lines
At least 110 nodes can be connected
High speed (up to 1 MBd)
High immunity against electromagnetic interference.
3. Applications
High-speed applications (up to 1 MBd) in trucks and busses.
4. Quick reference data
