GENERAL DESCRIPTION
The PCA82C252 is the interface between the CAN
protocol controller and the physical bus. It is primarily
intended for low-speed applications, up to 125 kBaud, in
passenger cars. The device provides differential transmit
capability but will switch in error conditions to a single-wire
transmitter and/or receiver.
PACKAGE
BAT
Thermally protected
Bus lines protected against transients in an automotive
environment
An unpowered node does not disturb the bus lines.
Low current sleep/standby mode with wake-up via the
bus lines
Power-on reset flag on the output.
