FEATURES
Fully compatible with the
“ISO 11898”
standard
High speed (up to 1 Mbaud)
Bus lines protected against transients in an automotive
environment
Slope control to reduce Radio Frequency Interference
(RFI)
Differential receiver with wide common-mode range for
high immunity against ElectroMagnetic Interference
(EMI)
Thermally protected
Short-circuit proof to battery and ground
Low-current standby mode
An unpowered node does not disturb the bus lines
At least 110 nodes can be connected.
APPLICATIONS
High-speed applications (up to 1 Mbaud) in cars.
GENERAL DESCRIPTION
The PCA82C250 is the interface between the CAN
protocol controller and the physical bus. The device
provides differential transmit capability to the bus and
differential receive capability to the CAN controller.
