PCA82C251
CAN transceiver for 24 V systems
Rev. 04 â 28 January 2010
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
 Fully compatible with the âISO 11898-24 Vâ 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.
