CAN controller interface
Objective specification
PCA82C250
FEATURES
• Fully compatible with the “ISO/DIS 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.

CHARACTERISTICS
VCC = 4.5 to 5.5 V; Tamb = −40 to +125 °C; RL = 60 Ω; I8 > −10 µA; unless otherwise specified.
All voltages referenced to ground (pin 2); positive input current; all parameters are guaranteed over the ambient
temperature range by design, but only 100% tested at +25 °C.
