DESCRIPTION
GENERAL DESCRIPTION
The TJA1050 is the interface between the Controller Area
Network (CAN) protocol controller and the physical bus.
The device provides differential transmit capability to the
bus and differential receive capability to the CAN
controller.
The TJA1050 is the third Philips high-speed CAN
transceiver after the PCA82C250 and the PCA82C251.
The most important differences are:
This makes the TJA1050 eminently suitable for use in
nodes that are in a power-down situation in partially
powered networks.
CC
CC
PACKAGE
Much lower electromagnetic emission due to optimal
matching of the output signals CANH and CANL
Improved behaviour in case of an unpowered node
No standby mode.
