CAN transceiver for 24 V systems

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.
