Datasheet

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.
