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

I Fully compatible with the “ISO 11898” standard

I High speed (up to 1 MBd)

I Bus lines protected against transients in an automotive environment

I Slope control to reduce Radio Frequency Interference (RFI)

I Differential receiver with wide common-mode range for high immunity against

ElectroMagnetic Interference (EMI)

I Thermally protected

I Short-circuit proof to battery and ground

I Low-current Standby mode

I An unpowered node does not disturb the bus lines

I At least 110 nodes can be connected

3. Applications

I High-speed automotive applications (up to 1 MBd).
